1A DC resistor of 40 Ω carries 3 A. What is the voltage across it?
A.120 V
B.43 V
C.13.3 V
D.360 V
Explanation: Ohm's law gives V = IR = 3 × 40 = 120 V. Voltage is the product of current and resistance for a purely resistive DC load.
2A 230 V DC heater dissipates 2.3 kW. What current does it draw?
A.10 A
B.100 A
C.0.1 A
D.5.29 A
Explanation: P = VI so I = P/V = 2300/230 = 10 A. Power in watts divided by voltage in volts yields current in amperes.
3The peak value of a sinusoidal AC voltage is 325 V. What is the approximate RMS value?
A.230 V
B.325 V
C.460 V
D.163 V
Explanation: For a sine wave, V_rms = V_peak/√2 ≈ 325/1.414 ≈ 230 V, the standard European single-phase RMS supply magnitude.
4An AC load takes 8 A at 230 V with a power factor of 0.8 lagging. What is the real power?
A.1472 W
B.1840 W
C.1150 W
D.2944 W
Explanation: Real power P = VI cosφ = 230 × 8 × 0.8 = 1472 W. The power factor scales the apparent power down to useful wattage.
5A single-phase load has S = 5 kVA and P = 4 kW. What is the reactive power Q?
A.3 kvar
B.1 kvar
C.9 kvar
D.4.5 kvar
Explanation: From the power triangle, Q = √(S² − P²) = √(25 − 16) = √9 = 3 kvar. Apparent, real and reactive power form a right triangle.
6A purely resistive 50 Ω load is supplied at 100 V RMS AC. What is the average power?
A.200 W
B.100 W
C.5000 W
D.2 W
Explanation: For a resistor, P = V²/R = 100²/50 = 200 W. With unity power factor, average power equals V_rms I_rms.
7Three identical 12 Ω resistors are connected in parallel across a 24 V DC source. What is the total current from the source?
A.6 A
B.2 A
C.0.5 A
D.72 A
Explanation: Each branch draws I = 24/12 = 2 A, so three branches draw 6 A. Equivalently R_eq = 4 Ω and I = 24/4 = 6 A.
8An inductive load draws 10 A at 400 V with cosφ = 0.6. What is the apparent power?
A.4 kVA
B.2.4 kW
C.3.2 kvar
D.6.67 kVA
Explanation: Apparent power S = VI = 400 × 10 = 4000 VA = 4 kVA. Cosφ is not needed for S; it is needed for real power.
9A balanced three-phase load takes 12 A line current from a 400 V line-to-line supply at unity power factor. What is the total real power (use √3 ≈ 1.732)?
A.approximately 8.3 kW
B.4.8 kW
C.14.4 kW
D.2.4 kW
Explanation: P = √3 × V_L × I_L × cosφ = 1.732 × 400 × 12 × 1 ≈ 8314 W ≈ 8.3 kW.
10The instantaneous voltage of a sine wave is v = 340 sin(ωt) volts. What is the peak-to-peak voltage?
A.680 V
B.340 V
C.240 V
D.170 V
Explanation: Peak-to-peak is twice the peak amplitude: 2 × 340 = 680 V. The expression already states the peak as 340 V.
