Answer:
Given:
Total "n" resistors have been provided.
To find:
Net resistance in case of parallel and series combinations.
Concept:
When we connect several resistance, we can think of another imaginary circuit where only one resistance (equal to the net resistance) has been used.
Calculation:
1st case:
Series combinations:
Net resistance = R + R + R +...... n times
=> Net resistance = n × R
=> Net resistance = nR
2nd case:
Parallel combination:
=> 1/R eq. = n/R
=> R eq. = R/n
So final answer :
Net resistance (series combination) = nR
Net resistance (parallel comb. ) = R/n
