Q: What is the unit of measurement for electrical resistance?

Ohm (?) — Resistance opposes current flow, measured in Ohms.

Q: Which of the following is the best conductor of electricity at room temperature?

Silver — Silver has the lowest resistance, allowing electrons to move easily.

Q: What does Ohm's Law state?

V = I * R — Ohm's Law defines the relationship between voltage, current, and resistance.

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

To limit current flow — A fuse protects the circuit by breaking the circuit if current exceeds the rated value.

Q: What is the unit of measurement for electrical power?

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

Q: Which of the following describes the relationship between voltage and current in a purely resistive circuit?

Voltage and current are in phase — In a resistive circuit, voltage and current rise and fall together.

Q: What type of circuit allows current to flow along multiple paths?

Parallel circuit — Parallel circuits provide multiple paths for current, allowing components to operate independently.

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

To store electrical energy — A capacitor stores energy in the form of an electric field.

Q: What is the SI unit for electric charge?

Coulomb (C) — The Coulomb is the standard unit to measure the quantity of electric charge.

Q: Which component is used to convert AC voltage to DC voltage?

Diode — Diodes allow current to flow in one direction, creating DC from AC when used in a rectifier circuit.
