Two resistances x and y are connected ...

Two resistances x and y are connected
i] in parallel and,
ii] in series. In which case the resultant resistance will be the less than either of the individual resistance?

Text Solution

Verified by Experts

In parallel combination, the resultant resistance will be less than either resistance.
In series combination, the resultant combination will be larger than both resistances.
