Question

Calculate the time required to produce 6750 Coulomb's by passing current of 4.5 amperes

Answer 1

The quantity of charge (or electricity) contained in a current running for a specified time can be calculated

$Q=I t$

which can be rearranged to t=Q/I

where; t = time in seconds

Q= charge in coulomb

I = current in ampere

so t=6750/4.5

$t= 1500sec$ or $25 min$
