Question

Derive the expression for equivalent in series and parallel connection circuit

Answer 1

$\huge\fbox\red{♡Answer}$

It is observed that the total current I, is equal to the sum of the separate currents through each branch of the combination. Thus, we may conclude that the reciprocal of the equivalent resistance of a group of resistances joined in parallel is equal to the sum of the reciprocals of the individuals resistances.
