A battery of 12 V supplies a current of 3 A to a lamp connected to it. The energy supplied to it in 15 minutes will be:

Correct option is C

The correct answer is: (C) 32400 J.

To calculate the energy supplied to the lamp, we can use the formula:

Energy (E)=Voltage(V) × Current(I) × Time(t)

Where:

• V=12 (Voltage)
• I = 3 A (Current)
• t = 15 minutes = 15×60=  900 second  (Time in seconds)

Now, substitute the values into the formula:

$$E = 12 \, \text{V} \times 3 \, \text{A} \times 900 \, \text{s}$$

$$E=32400 JE = 32400 \, \text{J}$$​​

Thus, the energy supplied is 32400 J.
