$(b)$ Calculate the current in a circuit, if $500 \,C$ of charge passes through it in $10$ minutes.
$(a)$ The direction of electric current is opposite to the direction of flow of electrons in a wire.
$(b)$ Given $Q=500 C$
$t=10$ minute
$=10 \times 60=600 s , I =?$
Using the relation
$I = Q / t=500 / 600=0. 83 A$
