What is the SI unit of electric potential difference?
- A.
Ohm
- B.
Joule
- C.
Coulomb
- D.
Volt
Correct Answer
D. VoltExplanation
The volt (V) is the standard unit of measurement for electric potential difference, commonly referred to as voltage. Electric potential difference is a measure of the electrical potential energy per unit charge in an electric circuit.Rate this question:

What is the formula to calculate electrical power?
- A.
P = W/V
- B.
P = IV
- C.
P = V/R
- D.
P = E/t
Correct Answer
B. P = IVExplanation
This formula expresses the relationship between power, current, and voltage in an electrical circuit. The power in a circuit can also be calculated using other related formulas, such as P = V²/R (where R is resistance) or P = I²R (where R is resistance). However, the formula P = IV is particularly useful when dealing with direct current (DC) circuits and is a fundamental equation in electrical engineering.Rate this question:

What does the term 'AC' in AC power supply stand for?
- A.
Alternating Current
- B.
Amplified Current
- C.
Alternating Charge
- D.
Amplified Charge
Correct Answer
A. Alternating CurrentExplanation
The term 'AC' in AC power supply stands for Alternating Current. AC power is a type of electrical current where the flow of electric charge periodically reverses direction. This reversal of direction occurs at a certain frequency, usually measured in hertz (Hz).Rate this question:

What is the purpose of a fuse in an electrical circuit?
- A.
To increase resistance
- B.
To control current
- C.
To generate electricity
- D.
To store electrical energy
Correct Answer
B. To control currentExplanation
The purpose of a fuse in an electrical circuit is to control current. A fuse is a safety device that is designed to protect electrical circuits and equipment from excessive current. It acts as a sacrificial element in the circuit, typically made of a material with a lower melting point than the rest of the circuit components.Rate this question:

What is the function of a transformer in electrical systems?
- A.
To store electrical energy
- B.
To convert AC to DC
- C.
To control current
- D.
To change voltage levels
Correct Answer
D. To change voltage levelsExplanation
The function of a transformer in electrical systems is to change voltage levels. A transformer is a device that transfers electrical energy between two or more circuits through electromagnetic induction. It consists of two coils of wire, known as the primary and secondary coils, which are usually wound around a common iron core.Rate this question:

What is the color coding for a live wire in electrical wiring?
- A.
Gray
- B.
Green
- C.
White
- D.
Red
Correct Answer
D. RedExplanation
The color coding for a live (hot) wire in electrical wiring varies by region and country. In many countries, including the United States and Canada, the standard color for a live wire is black, red, or any color other than green, white, or gray. These colors are used to indicate the presence of voltage and are associated with the active conductors in a power circuit.Rate this question:
