Q: What is the SI unit of electric current?

Ampere — Ampere (A) is the standard unit for measuring electric current.

Q: Which of the following describes the flow of electric charge?

Current — Electric current is defined as the rate of flow of electric charge.

Q: What is the unit of electrical resistance?

Ohm — Ohm (?) is the unit of electrical resistance, opposing current flow.

Q: What does 'AC' stand for in electrical terms?

Alternating Current — AC stands for Alternating Current, where current periodically reverses direction.

Q: What does 'DC' stand for in electrical terms?

Direct Current — DC stands for Direct Current, flowing in one direction only.

Q: Which of the following is a good conductor of electricity?

Copper — Copper is an excellent conductor due to its atomic structure.

Q: What is the purpose of a fuse in an electrical circuit?

To protect the circuit from overcurrent — A fuse breaks the circuit if the current exceeds a safe limit.

Q: What is voltage measured in?

Volts — Voltage is measured in Volts (V), representing electrical potential difference.

Q: Which component is used to store electrical energy?

Capacitor — A capacitor stores energy in an electric field.

Q: What is the relationship between voltage (V), current (I), and resistance (R) in a circuit?

V = I * R — Ohm's Law: Voltage (V) equals Current (I) times Resistance (R).
