1Ohm's law states that for a constant-temperature ohmic resistor, voltage V equals:
A.Current multiplied by resistance (V = I × R)
B.Current divided by resistance (V = I / R)
C.Resistance divided by current (V = R / I)
D.Current plus resistance (V = I + R)
Explanation: Ohm's law is V = I × R. Rearrangements give I = V / R and R = V / I. Adding current and resistance is not a valid electrical relationship.
2A 12 V DC supply is connected across a 6 Ω resistor. The current is:
A.0.5 A
B.2 A
C.18 A
D.72 A
Explanation: I = V / R = 12 V / 6 Ω = 2 A.
3The SI unit of electrical resistance is the:
A.Volt
B.Ampere
C.Ohm
D.Watt
Explanation: Resistance is measured in ohms (Ω). Volt is potential difference, ampere is current, and watt is power.
4Electric current is the flow of:
A.Charge per unit time
B.Force per unit area
C.Mass per unit volume
D.Energy per unit charge only
Explanation: Current I = Q / t (charge flow rate). Energy per unit charge is voltage, not current itself.
5Which material is typically a good electrical conductor?
A.Copper
B.Glass
C.Rubber
D.Dry wood
Explanation: Copper has free electrons and low resistivity, so it conducts well. Glass, rubber, and dry wood are insulators.
6The SI unit of electric current is the:
A.Volt
B.Ohm
C.Ampere
D.Farad
Explanation: Current is measured in amperes (A). Volt is voltage, ohm is resistance, and farad is capacitance.
7In a simple series circuit with one battery and two resistors, the same quantity through each resistor is:
A.Current
B.Voltage drop always equal regardless of R
C.Power always equal
D.Resistance
Explanation: Series elements share the same current. Voltage drops depend on each resistance; power depends on both V and I.
8A 100 Ω resistor dissipates heat when 50 mA flows through it. Approximate power is:
A.0.25 W
B.5 W
C.2 W
D.50 W
Explanation: P = I²R = (0.05)² × 100 = 0.0025 × 100 = 0.25 W. Always convert mA to amperes first.
9Two 10 Ω resistors in parallel across 10 V draw a total current of:
A.0.5 A
B.1 A
C.2 A
D.0.1 A
Explanation: Each resistor draws I = 10/10 = 1 A. Parallel currents add, so total = 2 A. Equivalent R = 5 Ω, I = 10/5 = 2 A.
10Potential difference is measured in:
A.Amperes
B.Ohms
C.Volts
D.Henries
Explanation: Potential difference (voltage) is measured in volts (V).
