electrical quantities Quiz Practice Quiz…

Q: Which of the following is the SI unit of electric current?

Ampere — The ampere (A) measures the rate of flow of electric charge.

Q: What electrical quantity is measured in volts (V)?

Voltage — Voltage, also known as potential difference, is measured in volts.

Q: Which of the following describes the opposition to the flow of current?

Resistance — Resistance is the opposition to the flow of electric current, measured in Ohms.

Q: What is the unit of electrical power?

Watt — Power is the rate at which electrical energy is transferred, and is measured in Watts.

Q: If a resistor has a voltage of 12V across it and a current of 2A flowing through it, what is its resistance?

6 Ohms — Using Ohm's Law (R=V/I), 12V / 2A = 6 Ohms.

Q: What is the relationship between voltage, current, and resistance?

Ohm's Law — Ohm's Law (V=IR) describes this fundamental relationship.

Q: What does a multimeter primarily measure?

Voltage, Current, and Resistance — A multimeter is used to measure Voltage, Current, and Resistance.

Q: Which of the following units is used to measure electrical energy?

Joule — Electrical energy is measured in Joules (J).

Q: What is the definition of capacitance?

The ability to store electrical energy in an electric field — Capacitance stores electrical energy in an electric field.

Q: The unit of capacitance is the:

Farad — The Farad (F) is the unit of capacitance.
