Question

Prove that when a number of resistors are connected in series, the equivalent resistance of the combination of resistors is equal to the sum of the individual resistances of the resistors.

Answer 1

Suppose three resistors R1 R2 and R3 are connected in series , their equivalent resistance will be equal to the sum of individual resistances.

The equivalent resistance will be maximum than the individual resistance.

Re=R1+R2+R3
