Question

If 400 Milli ampere current flows through the bulb for 1 minute how many electron will pass through it

Answer 1

Explanation:

I = n×e÷ t

where n is the no. of electrons and e isthe charge on an electron that is (1.6×10-19)

mili amp = 10-³amp

(400÷1000)= n × 1.6×10-19 ÷ 60 here we used 60 sec instead of 1 min

now calculate theans
