- B.
Natural resources that cannot be replaced once they are used up
- C.
Hydrogen Energy
- D.
Uranium
Correct Answer
A. Resources that can be continually reproduced over a relatively short period of timeExplanation
The correct answer is "resources that can be continually reproduced over a relatively short period of time." This definition refers to resources that can be replenished or regenerated naturally, ensuring their availability for future use. These resources are sustainable and can be used without depleting their stock. An example of a renewable resource is Hydrogen Energy, which can be produced from various sources like water and biomass.Rate this question:

What is current electricity?
- A.
Continuous flow of electrons in a circuit
- B.
A charge that is built up then dispersed
- C.
Energy stored within an item, that it then released
Correct Answer
A. Continuous flow of electrons in a circuitExplanation
Current electricity refers to the continuous flow of electrons in a circuit. When a circuit is complete and connected to a power source, such as a battery, the electrons flow from the negative terminal of the source to the positive terminal. This flow of electrons creates an electric current, which can be used to power various devices and appliances. It is important to note that current electricity requires a closed loop or circuit for the electrons to flow continuously.Rate this question:

Unlike ___________________, current electricity needs an energy source and a complete path to follow.
Correct Answer
static electricityExplanation
Static electricity is different from current electricity because it does not require an energy source or a complete path to follow. Static electricity occurs when there is a buildup of electric charge on the surface of an object, causing it to attract or repel other objects. In contrast, current electricity involves the flow of electric charge through a conductor, such as a wire, which requires an energy source, such as a battery or power plant, and a complete circuit for the electricity to flow.Rate this question:

_________________ is the degree to which a substance resists the flow of electric current through it. All substances resist electron flow to some extent.
Correct Answer
ResistanceExplanation
Resistance is the measure of how much a substance opposes the flow of electric current. It is a property exhibited by all substances to some extent. The higher the resistance, the more difficult it is for electric current to pass through the substance. Resistance is determined by factors such as the material's conductivity, length, and cross-sectional area.Rate this question:
- 5.
An _______ is a device for measuring resistance.
Correct Answer
ohmmeterExplanation
An ohmmeter is a device used to measure resistance in an electrical circuit. It works by applying a known voltage to the circuit and measuring the resulting current. By using Ohm's Law (V = IR), the ohmmeter can calculate the resistance based on the measured current and the applied voltage. This device is commonly used in electronics and electrical engineering to test the integrity and quality of resistors and other components in a circuit.Rate this question:
- 6.
What is measured by volts?
- A.
Current
- B.
Potential Difference
- C.
Resistance
- D.
Electricity
- E.
None of the above
Correct Answer
B. Potential DifferenceExplanation
The correct answer is potential difference. Volts is the unit used to measure potential difference, which refers to the difference in electric potential energy between two points in an electric circuit. It represents the amount of work done per unit charge in moving a charge from one point to another. Current, resistance, and electricity are all related concepts in electricity, but they are not directly measured in volts.Rate this question:

- 7.
What is a proton
- A.
A positively charged particle
- B.
A negatively charged particle
- C.
A neutral particle
- D.
An atom
- E.
None of these
Correct Answer
A. A positively charged particleExplanation
A proton is a subatomic particle that carries a positive charge. It is one of the building blocks of an atom, along with neutrons and electrons. Protons are located in the nucleus of an atom and have a mass approximately 1,836 times greater than that of an electron. They play a crucial role in determining the atomic number and identity of an element.Rate this question:

_____________ can flow when there is a complete circuit.
Correct Answer
Electricity, Current ElectricityExplanation
Electricity can flow when there is a complete circuit because a complete circuit provides a continuous path for the flow of electric current. In a complete circuit, there is a source of electricity, such as a battery or power outlet, which provides the necessary voltage to push the electrons through the circuit. The circuit also includes conductive materials, such as wires, that allow the electrons to flow easily. Without a complete circuit, there would be breaks or gaps in the path, preventing the flow of electricity. Therefore, the presence of a complete circuit is essential for the flow of electricity.Rate this question:
- 9.
Materials through which electricity can pass are called ___________ conductors.
Correct Answer
electricalExplanation
The question asks for the term used to describe materials that allow electricity to pass through them. The correct answer is "electrical," which is an adjective that describes something related to electricity. Therefore, materials that allow electricity to pass through them are called "electrical conductors."Rate this question:
- 10.
____________ is the movement of electrons within a substance caused by nearby charged objects, without direct contact between the substance and the object.
Correct Answer
InductionExplanation
Induction is the process by which the movement of electrons occurs within a substance due to the presence of nearby charged objects, even without direct contact between the substance and the object. This phenomenon is caused by the electric field produced by the charged objects, which induces a redistribution of electrons within the substance. As a result, the substance acquires a temporary charge imbalance, leading to the movement of electrons.Rate this question:
- 11.
What happens when a switch is turned off?
- A.
Electricity stops flowing from the switch and therefore the circuit is broken, providing no electricity to the object being powered
- B.
Electricity is able to flow through the circuit powering an electrical device
- C.
Electricity is not able to flow through the circuit but it can still power an electrical device
- D.
Electricity is able to flow through the circuit but it cannot power an electrical device
Correct Answer
A. Electricity stops flowing from the switch and therefore the circuit is broken, providing no electricity to the object being poweredExplanation
When a switch is turned off, electricity stops flowing from the switch, which means that the circuit is broken. As a result, no electricity is provided to the object being powered.Rate this question:

Which one is the odd one out?
- A.
Glass
- B.
Tin
- C.
Copper
- D.
Silver
Correct Answer
A. GlassExplanation
The odd one out is "Glass" because it is the only material in the list that is not a metal. Tin, Copper, and Silver are all metals, whereas Glass is an amorphous solid.Rate this question:

What is in an atom?
- A.
Protons, Electrons, Neutron and a Nucleus
- B.
Protons and Electrons
- C.
A nucleus and a proton
- D.
Protons and Neutrons
- E.
Protons, Electrons Neutron
Correct Answer
E. Protons, Electrons NeutronExplanation
An atom consists of protons, electrons, and neutrons. Protons carry a positive charge and are located in the nucleus of the atom. Electrons carry a negative charge and orbit around the nucleus. Neutrons have no charge and are also located in the nucleus. Together, these three particles make up the structure of an atom.Rate this question:
