Question

If a current of 1A flows through a circuit for 1.5hrs,then the charge flowing through the conductor is​

Answer 1

Solution:

Current, I = 1 A

Time, t =1.5 hours

Convert in sec we get

Time, t = 1.5 × 60 × 60 s

= 7200 s

Use formula

Charge Q = It

Plug the values we get

= 0.5 A × 7200 s

= 3600 Coulombs

Number of electrons = total charge / charge on 1 electrons

= 3600/(1.6 ×10 19)

=2.25 × 1022 electrons
