When three identical bulbs are connected in series, the consumed power is $10$ W. If they are now connected in parallel then the consumed power will be:
1. $30$ W
2. $90$ W
3. $\frac{10}{3}$ W
4. $270$ W

In a hot wire ammeter due to the flowing of the current, the temperature of the wire is increased by $5^{\circ}$ C. If the value of the current is doubled, then the increase in temperature will be:
1. $15^{\circ}$ C
2. $20^{\circ}$ C
3. $25^{\circ}$ C
4. $30^{\circ}$ C

The current in $8~\Omega$ resistance is (in the figure below):

1. $0.69$ A
2. $0.92$ A
3. $1.30$ A
4. $1.6$ A

If the power dissipated in $5~\Omega$ is $20~\text{W}$ then the power dissipated in $4~\Omega$ is:
   
1. $4~\text{W}$
2. $6~\text{W}$
3. ​​​​​​​$10~\text{W}$ 
4. ​​​​​​​$20~\text{W}$

The terminal potential difference of a cell is greater than its emf when:

The net resistance of the circuit between $A$ and $B$ is:

A car battery of emf $12~\text{V}$ and internal resistance $5\times 10^{-2}~\Omega$ receives a current of $60~\text{A}$ from an external source. The terminal voltage of the battery is:

If there are two bulbs of $(40~\text{W},200~\text{V}),$ and $(100~\text{W},200~\text{V}),$ then the correct relation for their resistance is:
1. $R_{40}<R_{100}$
2. $R_{40}>R_{100}$
3. $R_{40}=R_{100}$
4. no relation can be predicted

According to the Faraday Law of electrolysis, the mass deposited at electrode will be proportional to:

1. m ∝ I²

2. m ∝ Q

3. m ∝ Q²

4. 'm' does not depend on Q
