Combinations of Resistance:
There are two types of resistance combinations.
(i) Series Combination In this combination, different resistances are connected end to end.
Equivalent resistance can be obtained as the formula,
NOTE: The total resistance in the series combination is more than the greatest resistance in the circuit.
(ii) Parallel Combination In this combination, first end of all the resistances are connected to one point and last end of all the resistances are connected to other point. Equivalent resistance can be obtained by the formula
NOTE: The total resistance in parallel combination is less than the least resistance of the circuit.
20. If n identical resistors each of resistance r are connected in
(i) series combination, Req = nr
(ii) parallel combination, Req = r/n
