Question

A 60 watt bulb carries a current of 0.5 A. Total charge passing through in one hour is : 

(a) 3600 C 

(b) 3000 C 

(c) 2400 C 

(d) 1800 C

Answer 1

Correct option (d) 1800 C

Explanation:

From the formula of current and charge. charge = current × time 

or q = it (given i = 0.5 A, time t = 1 hour = 60 × 60 sec) 

or q = 0.5 × 60 × 60 

= 1800 coulomb
