Sample Maharashtra HSC Electrical Maintenance (Bifocal) Practice Questions

Try these sample questions to test your Maharashtra HSC Electrical Maintenance (Bifocal) exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Ohm’s law states that, for a metallic conductor at constant temperature, the current I is:
A.Inversely proportional to voltage V
B.Directly proportional to voltage V
C.Equal to resistance R
D.Independent of resistance R
Explanation: Ohm’s law: V = I R, so I is directly proportional to V when R is constant (fixed temperature for metals).
2A 12 V battery drives 2 A through a resistor. The resistance is:
A.6 Ω
B.24 Ω
C.10 Ω
D.0.17 Ω
Explanation: R = V/I = 12/2 = 6 Ω.
3Electrical power delivered to a pure resistive load is given by:
A.P = V/I
B.P = V I
C.P = V + I
D.P = I/R
Explanation: Instantaneous/average power for a DC resistive load is P = V I (also P = I²R = V²/R).
4A 230 V heater draws 5 A. Its power consumption is approximately:
A.46 W
B.1150 W
C.235 W
D.0.022 kW
Explanation: P = V I = 230 × 5 = 1150 W (about 1.15 kW).
5Energy consumed by a 2 kW load running for 3 hours is:
A.6 kWh
B.2 kWh
C.0.67 kWh
D.5 kWh
Explanation: Energy (kWh) = power (kW) × time (h) = 2 × 3 = 6 kWh.
6Three 6 Ω resistors in series have an equivalent resistance of:
A.2 Ω
B.6 Ω
C.18 Ω
D.36 Ω
Explanation: Series resistances add: R_eq = 6 + 6 + 6 = 18 Ω.
7Two equal resistors of 10 Ω each connected in parallel have equivalent resistance:
A.20 Ω
B.5 Ω
C.10 Ω
D.100 Ω
Explanation: For two equal R in parallel, R_eq = R/2 = 5 Ω.
8A copper wire of resistance 4 Ω is stretched to twice its original length, keeping volume constant. Approximate new resistance is:
A.2 Ω
B.4 Ω
C.8 Ω
D.16 Ω
Explanation: R ∝ L/A. Doubling length halves area (constant volume), so R multiplies by 4 → 16 Ω.
9For wire sizing estimates, current-carrying capacity mainly increases when the conductor:
A.Cross-sectional area increases
B.Length increases
C.Insulation colour changes
D.Ambient temperature rises sharply
Explanation: Larger cross-section lowers resistance and heating for a given current, raising ampacity (other factors equal).
10A single-phase circuit supplies 2.3 kW at 230 V with unity power factor. Approximate line current is:
A.1 A
B.10 A
C.100 A
D.0.1 A
Explanation: At unity pf, I = P/V = 2300/230 = 10 A.
