Q: Which of the following is a passive electrical component?

Resistor — Resistors consume power, unlike active components which can amplify.

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

Ampere (A) — Ampere (A) measures the flow of electric charge.

Q: What does a resistor do in a circuit?

Opposes the flow of current — Resistors limit current flow based on their resistance value.

Q: What is the function of a capacitor?

To store electrical energy — Capacitors store energy in an electric field.

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

Ohm — Resistance is measured in Ohms (?).

Q: What type of component converts AC voltage to a different AC voltage level?

Transformer — Transformers use electromagnetic induction to step up or step down voltage.

Q: What does a diode primarily do in a circuit?

Allows current flow in one direction — Diodes conduct current in only one direction.

Q: Which component is used to store electrical energy in an electric field?

Capacitor — Capacitors store energy in an electric field created by charge buildup.

Q: What is the primary purpose of a transformer?

To change AC voltage levels — Transformers are used for voltage step-up or step-down.

Q: What is the relationship between voltage, current, and resistance according to Ohm's Law?

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