A complete path through which electricity flows is a(n)
-
Circuit
-
Series
-
Cell
-
Fuse
Correct Answer
A. CircuitExplanation
A circuit refers to a complete path through which electricity flows. It includes various components such as wires, switches, and resistors that are connected in a loop or series. This allows the electricity to flow continuously from the power source to the load and back. A circuit is essential for the proper functioning of electrical devices and systems, as it ensures the uninterrupted flow of current.Rate this question:

The plastic around an electrical wire that keeps you from getting a shock is an example of a(n)
-
Conductor
-
Fuse
-
Insulator
-
Circuit breaker
Correct Answer
A. InsulatorExplanation
The plastic around an electrical wire acts as an insulator, preventing the flow of electric current and thus keeping you from getting a shock. Insulators are materials that do not conduct electricity easily, and they are used to protect against electrical accidents by providing a barrier between the current-carrying wire and any conductive surfaces or individuals.Rate this question:

A thin wire strip that melts easily to keep too much electric current from flowing through wires is a(n)
-
Insulator
-
Overload
-
Fuse
-
Circuit
Correct Answer
A. FuseExplanation
A fuse is a thin wire strip that melts easily when too much electric current flows through it. This melting of the wire breaks the circuit and prevents further flow of current, protecting the wires from damage caused by overload. Therefore, a fuse is used as a safety device to prevent excessive current from flowing through wires.Rate this question:

To make light, a flashlight needs a bulb, a switch, and a(n)
-
Parallel
-
Insulator
-
Cell
-
Current
Correct Answer
A. CellExplanation
A flashlight needs a cell to provide the necessary electrical energy to power the bulb and produce light. The cell acts as a source of direct current (DC) electricity, which flows through the circuit when the switch is turned on. Without the cell, there would be no source of power to generate light in the flashlight.Rate this question:

A crane in a junkyard can separate iron and steel from paper using a(n)
-
Generator
-
Volt
-
Electromagnet
-
Transformer
Correct Answer
A. ElectromagnetExplanation
An electromagnet can be used in a crane in a junkyard to separate iron and steel from paper. When an electric current is passed through the coils of the electromagnet, it creates a magnetic field. The magnetic field attracts the iron and steel materials, allowing them to be separated from the paper. This is possible because iron and steel are magnetic materials, while paper is not. The electromagnet provides a temporary magnetic force that can be controlled and turned on/off as needed for the separation process.Rate this question:

A device that is used to change the voltage of electricity is a(n)
-
Generator
-
Volt
-
Electromagnet
-
Transformer
Correct Answer
A. TransformerExplanation
A transformer is a device that is used to change the voltage of electricity. It consists of two coils of wire, known as the primary and secondary coils, which are wound around a core. When an alternating current passes through the primary coil, it creates a changing magnetic field in the core. This changing magnetic field induces a voltage in the secondary coil, resulting in a change in voltage. Transformers are commonly used in electrical power distribution systems to step up or step down the voltage for transmission and use in different applications.Rate this question:

A unit for measuring the force that makes negative charges flow is called a(n)
-
Generator
-
Volt
-
Electromagnet
-
Transformer
Correct Answer
A. VoltExplanation
A unit for measuring the force that makes negative charges flow is called a volt. The volt is the SI unit of electric potential difference and electromotive force. It represents the amount of electrical potential energy per unit charge. In other words, it measures the strength or intensity of the electric force that causes negatively charged particles to move in a circuit. Generators, electromagnets, and transformers are all devices that can generate or manipulate electric currents, but they are not units of measurement for the force itself.Rate this question:

A magnet’s pull is strongest at its
-
Volt
-
Poles
-
Field
-
Generator
Correct Answer
A. PolesExplanation
A magnet's pull is strongest at its poles because the magnetic field lines are concentrated and closer together at the poles. This means that the magnetic force exerted by the magnet is stronger at the poles compared to other parts of the magnet. The poles are the regions where the magnetic field lines emerge (north pole) or converge (south pole), resulting in a stronger magnetic force.Rate this question:

A bulb gets dimmer when a second bulb is added to the circuit. The bulbs are wired in a(n)
-
Series circuit
-
Parallel circuit
Correct Answer
A. Series circuitExplanation
In a series circuit, the current flows through each component in the same path. When a second bulb is added to the circuit, the total resistance increases, causing the current to decrease. As a result, the bulbs receive less current and therefore become dimmer. In a parallel circuit, each component has its own path for the current to flow, so adding a second bulb would not affect the current flowing through the first bulb, and it would not get dimmer.Rate this question:

A material electricity flows through easily is a(n)
-
Insulator
-
Fuse
-
Conductor
-
Resistor
Correct Answer
A. ConductorExplanation
A material that electricity flows through easily is called a conductor. Conductors have a high number of free electrons that can move freely within the material, allowing electric current to flow easily. Examples of conductors include metals like copper and aluminum.Rate this question:

Which is NOT an example of the uses of an electromagnet?
-
Separating scrap iron from other garbage
-
Ringing a door bell
-
Finding which direction is North
-
Picking metal splinters out of skin
Correct Answer
A. Finding which direction is NorthExplanation
Finding which direction is North is not an example of the uses of an electromagnet. Electromagnets are used in various applications such as separating scrap iron from other garbage, ringing a doorbell, and picking metal splinters out of the skin. However, determining the direction of North typically involves the use of a compass, which relies on the Earth's magnetic field and does not require an electromagnet.Rate this question:

A balloon sticks to a wall after being rubbed on a sweater because of
-
Magnetism
-
Static electricity
-
Mechanical energy
-
Chemical energy
Correct Answer
A. Static electricityExplanation
When a balloon is rubbed on a sweater, it gains a static electric charge. The friction between the balloon and the sweater causes the transfer of electrons, resulting in an excess of negative charge on the balloon. This creates an imbalance of charges, with the balloon becoming negatively charged and the wall becoming positively charged. Opposite charges attract each other, causing the balloon to stick to the wall. This phenomenon is known as static electricity, where electric charges build up on the surface of an object and can cause attractive or repulsive forces between objects.Rate this question:
