Question

A current of 1A is drawn by a filament of an electric bulb for 10 minutes. Find the number of electric charge
that flows through the circuit

Answer 1

Given:

Ampere (I) =1 A

Time (t) =10 minutes

To Find:

Electric charge(Q)

Solution:

Q=I /t

Q=1/10

Q=0.1 coulomb.

0.1 coulomb charge will flows through the circuit.

Answer 2

current= charge/time , time =10min.(10×60 sec) current is 1A, then charge is current×time, charge =1×600, charge=600coulamb, charge=no.of electric charge×electronic charge here electronic charge=1.6×20^-19 c , and charge we found in above, then no. of electric charge = 600/1.6×10^-19, no.elctric charge = 375×10^19
