Quiz - Introduction To Electricity - Handout

Explanation
Watt-hours is a measurement of power. Power is the rate at which energy is consumed or produced, and it is measured in watts. Watt-hours specifically measures the amount of energy used or produced over a period of time. It is calculated by multiplying the power in watts by the time in hours. Therefore, watt-hours is a unit that quantifies the energy potential or consumption, making it the correct answer in this case.

Explanation
Voltage is the measurement of energy potential. It represents the amount of potential energy that a unit of charge possesses. Voltage is responsible for driving the flow of electric current in a circuit. It is the force that pushes the electrons through a conductor, creating a flow of charge. The higher the voltage, the greater the energy potential and the stronger the push on the charge carriers. Therefore, voltage is a measure of the energy that can be transferred or transformed in an electrical circuit.

Explanation
Voltage is the correct answer because it represents the potential difference created between positive and negative elements. Voltage is a measure of the electric potential energy per unit charge, and it indicates the force or pressure that drives electric current through a circuit. It is measured in volts and is a fundamental concept in understanding electrical circuits and systems.

Explanation
Solar panels produce direct current (DC) electricity. This means that the flow of electric charge is always in one direction, from the positive terminal to the negative terminal. Direct current is the type of current used in most electronic devices and is also the type of current that can be stored in batteries. Alternating current (AC), on the other hand, periodically changes direction, flowing back and forth. AC is the type of current that is typically used in household electrical systems. However, solar panels themselves generate DC current, which needs to be converted to AC using an inverter before it can be used in homes or businesses.

Explanation
The given question asks if the light bulb will work under the wiring arrangement. The answer "Yes" implies that the light bulb will indeed work under the given wiring arrangement.

Explanation
The given answer is "Series" because in a series circuit, the components are connected one after another, forming a single path for the current to flow. In this type of circuit, the current remains the same throughout, but the voltage drops across each component add up.

Explanation
The type of current found in our homes is alternating current. Alternating current (AC) is the flow of electric charge that periodically reverses direction. It is the most commonly used type of current for powering household appliances and electrical devices. Unlike direct current (DC), which flows in only one direction, AC constantly changes direction, typically at a frequency of 50 or 60 cycles per second. This allows for efficient transmission of electricity over long distances and easy conversion to different voltage levels.
