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 is a good conductor of electricity?

Copper — Copper is a metal and allows electricity to flow easily due to its free electrons.

Q: What does the 'V' in Ohm's Law (V = IR) represent?

Voltage — V stands for Voltage, representing the potential difference across a component.

Q: What is the unit of electrical resistance?

Ohm (?) — Electrical resistance is measured in Ohms, representing the opposition to current flow.

Q: Which component stores electrical energy?

Capacitor — A capacitor stores energy in an electric field.

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

V = IR — Ohm's Law: Voltage (V) equals Current (I) multiplied by Resistance (R).

Q: What is the SI unit of electric power?

Watt (W) — Electric power is measured in Watts.

Q: Which of the following is a type of electrical circuit?

All of the above — All options are valid circuit types.

Q: What type of charge does an electron carry?

Negative — Electrons carry a negative charge.

Q: In a series circuit, what happens to the current?

It is constant — The current is the same through all components in a series circuit.
