we know that,
If resistors are connected in parallel then the potential difference is same and current passed to each resistor is different.
- V = potential difference
- I = current
- R = resistance
According to ohm's Law:-
From eq. (i) ,(ii) , and (iii)
we get,
So,
expression for the equivalent resistance R1 R2 and R3 are connected in parallel is :-
