1.  
A current of 2 A flows for 5 minutes. The charge passed is:

Correct Answer: A [600 C]

Explanation:

Answer: 600 C. Q = It = 2 × 300.

2.  
Resistors of 4 Ω, 6 Ω and 10 Ω are joined in series. The equivalent resistance is:

Correct Answer: C [20 Ω]

Explanation:

Answer: 20 Ω. Add them.

3.  
Two resistors of 12 Ω each are joined in parallel. The equivalent resistance is:

Correct Answer: B [6 Ω]

Explanation:

Answer: 6 Ω. R/n = 12/2.

4.  
An electric iron of 1000 W is used for 2 hours a day for 30 days. The energy used is:

Correct Answer: D [60 units]

Explanation:

Answer: 60 units. 1000 × 2 × 30/1000 = 60 kWh.

5.  
Match the followingMatch the column:
P. Volt Q. Ohm R. Watt S. Coulomb
1. Power 2. Charge 3. Potential difference 4. Resistance

Correct Answer: B [P-3, Q-4, R-1, S-2]

Explanation:

Answer: P-3, Q-4, R-1, S-2. Each unit with its quantity.

6.  
Assertion–ReasonAssertion (A): A copper wire is not used as a fuse wire.
Reason (R): Copper has a high melting point and low resistivity.

Correct Answer: C [Both A and R are true and R explains A]

Explanation:

A fuse needs a low melting point.

7.  
The resistance of an appliance rated 220 V, 1000 W is:

Correct Answer: D [48.4 Ω]

Explanation:

Answer: 48.4 Ω. V²/P = 48400/1000.

8.  
Arrange in orderArrange in increasing order of resistivity: nichrome, copper, silver, aluminium

Correct Answer: A [silver < copper < aluminium < nichrome]

Explanation:

Silver 1.60 < copper 1.62 < aluminium 2.63 (× 10⁻⁸) < nichrome 100 × 10⁻⁶ Ω m.

9.  
Two-quantity comparisonTwo-quantity comparison (same 220 V supply):
Quantity I: resistance of a 60 W bulb
Quantity II: resistance of a 100 W bulb

Correct Answer: A [Quantity I > Quantity II]

Explanation:

R = V²/P – the lower wattage has the higher resistance (807 Ω vs 484 Ω).

10.  
True/false countHow many of these contain an electric motor?
I. Ceiling fan
II. Mixer-grinder
III. Filament bulb
IV. Water pump

Correct Answer: D [3]

Explanation:

The bulb uses the heating effect.

11.  
Diagram-basedIn the circuit shown, the current drawn from the 12 V battery is (ignore the ammeter's resistance):

Correct Answer: A [2 A]

Explanation:

6 Ω ∥ 6 Ω = 3 Ω; total 2 + 3 + 1 = 6 Ω; I = 12/6 = 2 A.

12.  
The direction of the force on a current-carrying conductor in a magnetic field is given by:

Correct Answer: B [Fleming's left-hand rule]

Explanation:

Answer: Fleming's left-hand rule. Left hand – motor effect.

13.  
The magnetic field inside a long current-carrying solenoid is:

Correct Answer: C [nearly uniform]

Explanation:

Parallel, evenly spaced field lines inside.

14.  
The earth wire is connected to the:

Correct Answer: A [metal body of an appliance]

Explanation:

Leakage current goes to the ground instead of through a person.

15.  
The device that converts mechanical energy into electrical energy is the:

Correct Answer: B [generator]

Explanation:

Answer: generator. Electromagnetic induction.
