Multiple Choice Questions
1. Which of the following best describes an electrical
circuit?
A. A closed path through which current can flow
B. Any path for mechanical motion
C. A device that stores energy only
D. A resistor connected to a battery
Rationale: An electrical circuit requires a closed loop allowing
current flow.
2. What is the basic function of an electrical circuit?
A. To transfer energy to components
B. To increase resistance only
C. To create voltage only
D. To measure current only
Rationale: Circuits transfer energy from a source to
components like resistors, capacitors, and loads.
3. Which quantity represents the flow of electric charge?
A. Current
B. Voltage only
C. Resistance only
D. Power only
Rationale: Current (I) is the rate of flow of electric charge
(Coulombs per second).
4. Which law relates voltage, current, and resistance?
A. Ohm’s Law
, B. Kirchhoff’s Voltage Law only
C. Kirchhoff’s Current Law only
D. Faraday’s Law only
Rationale: Ohm’s Law: V=I⋅RV = I \cdot RV=I⋅R.
5. Which component stores energy in a magnetic field?
A. Inductor
B. Capacitor only
C. Resistor only
D. Switch only
Rationale: Inductors store energy in a magnetic field created
by current flow.
6. Which component stores energy in an electric field?
A. Capacitor
B. Inductor only
C. Resistor only
D. Battery only
Rationale: Capacitors store energy in an electric field
between their plates.
7. Which is a passive circuit element?
A. Resistor
B. Battery only
C. Voltage source only
D. Operational amplifier only
Rationale: Passive elements do not generate energy;
resistors, capacitors, and inductors are examples.
