In a series combination of resistors, the effective resistance is lesser than any of the individual resistances.
Assertion (A): When resistors are connected in series, the effective resistance of the combination is greater than the resistances of the individual resistors.
Reason (R): When the resistors are connected in series, the effective length increases and the resistance is directly proportional to the length.
For n resistors of equal resistances in combination, parallel connection gives larger effective resistance than the series connection.
the effective resistance of two resisotrs in parallel is 7.5ohm . their effective resistance in series is 40 ohm . claculate their individual resistance of resistors
Assertion (A): When resistors are connected in parallel, the effective resistance of the combination is less than the individual resistances.
Reason (R): When resistors are connected parallel, the effective area of cross-section increases and the resistance is inversely proportional to the area of cross-section.
