Answer 1

Question : when an electric lamp is connected to 12 V battery it draws a current of 0.5 A the power of lamp is ?


Solution :

In this question , It is Given that an electric lamp is connected to 12 V battery it draws a current of 0.5 A.


Given :

V = 12 V

Current = 0.5 A


To Find : Power of Lamp = ?


We know that Formula of Powder = V × I


•°• P = VI

✏ P = 12 × 0.5

✏ P = 6 watt
