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

To protect the circuit from overcurrent. — Fuses are designed to break the circuit if the current exceeds a safe level.

Q: In a series circuit, what happens if one component fails?

The entire circuit breaks. — A break in a series circuit interrupts the flow of current throughout the circuit.

Q: Which of the following wire gauges is typically the largest (thickest)?

10 AWG — AWG stands for American Wire Gauge. Smaller numbers represent thicker wires.

Q: What is the purpose of a ground wire in a circuit?

To provide a safety path to earth. — The ground wire provides a low-resistance path for fault current to return to the source.

Q: What does a multimeter measure?

Voltage, current, and resistance. — A multimeter is a versatile tool for measuring several electrical properties.

Q: In a parallel circuit, how is the voltage across each branch related?

It is the same. — The voltage is consistent across all parallel branches.

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

Ampere (A) — Current is measured in amperes, often abbreviated as amps.

Q: What is the difference between a normally open (NO) and a normally closed (NC) switch?

NO is open by default, NC is closed. — NO switches are open until activated, NC are closed until activated.

Q: Which of the following is a common safety practice when working with electrical circuits?

Wearing appropriate safety glasses and gloves. — Safety glasses and gloves protect against electrical hazards.

Q: What is the purpose of insulation on electrical wires?

To prevent short circuits and protect users from shock. — Insulation provides a barrier to contain the current and prevent contact with conductors.
