Q: What is the SI unit of electric current?

Ampere (A) — Electric current is measured in Amperes, named after André-Marie Ampère.

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

Current — Electric current is the rate of flow of electric charge, typically measured in Amperes.

Q: What is the SI unit of electrical resistance?

Ohm (?) — Electrical resistance is measured in Ohms, named after Georg Ohm.

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

V = I * R — This is Ohm's Law: Voltage equals current multiplied by resistance.

Q: What does a capacitor primarily store?

Electric charge — A capacitor stores electric charge in an electric field.

Q: What is the SI unit of electric power?

Watt (W) — Electric power is measured in Watts, named after James Watt.

Q: Which component opposes the flow of current in a circuit?

Resistor — A resistor opposes the flow of current; it limits current flow.

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

To protect the circuit from overcurrent — A fuse is a safety device designed to break the circuit if excessive current flows.

Q: Which of the following is a unit of electrical energy?

Joule — Electrical energy is typically measured in Joules or kilowatt-hours.

Q: What type of charge does an electron carry?

Negative — An electron carries a negative electrical charge.
