- 10 A
- 0.5 A
- 2 A
- 5 A
Show answer and explanation
Answer: C. 2 A
I = Q/t = 10/5 = 2 A.

If cost of one unit of electricity is Rs. 10, then cost of using a 50 W bulb for 240 hours is:
- Rs. 29
- Rs. 43
- Rs. 120
- Rs. 240
Show answer and explanation
Answer: C. Rs. 120
Energy = 50 × 240 / 1000 = 12 kWh (units); cost = 12 × 10 = Rs. 120.
A 1 Ω resistor in 20 s consuming 2 ampere current will require (energy):
- 40 J
- 80 J
- 10 J
- 12 J
Show answer and explanation
Answer: B. 80 J
W = I²Rt = 2² × 1 × 20 = 80 J (i.e. 4 W for 20 s).
Which factor increases the resistance of a conductor?
- Increase in area
- Use of good conductor
- Increase in length
- Decrease in temperature
Show answer and explanation
Answer: C. Increase in length
R = ρL/A — resistance increases with length and decreases with area.
How long does it take a current of 50 mA to transfer 10 C charge?
- 200 s
- 300 s
- 400 s
- 50 s
Show answer and explanation
Answer: A. 200 s
t = Q/I = 10/0.05 = 200 s.
Ohm's law is obeyed by:
- a diode
- a filament bulb
- a metallic conductor at constant temperature
- a thermistor
Show answer and explanation
Answer: C. a metallic conductor at constant temperature
Ohm's law (V ∝ I) holds for metallic conductors whose temperature and physical state remain constant.
Calculate the total e.m.f. of three cells of 1.5 V when they are connected in: (a) series, (b) parallel.
Show model answer
(a) Series: e.m.f.s add: E = 1.5 + 1.5 + 1.5 = 4.5 V
(b) Parallel (identical cells): the e.m.f. stays the same: E = 1.5 V (but the combination can supply more current / last longer).
A bulb is connected to a 6 V battery and draws 2 A current. Find resistance.
Show model answer
R = V/I = 6/2 = 3 Ω
