Question

In series combination of resistors which of the following quantity remains the same A) Current B) Voltage

Answer 1

The correct option is (a) "current".

Explanation:

In series combination of resistors, current flowing throughout each and every resistor is same. Voltage throughout each resistor divides. The equivalent resistance in this case is given by the formula as follow :

$R=R_1+R_2+.....+R_n$

Hence, the correct option is (a) "current".

Answer 2

Given that,

In series combination of resistance.

(A), Current :

In the series combination of resistance then the current remains same in the each part of the circuit.

In the parallel combination of resistance then the current does not remain same in the each part of the circuit.

(B). Voltage :

In the series combination of resistance then the voltage does not remain same in the each part of the circuit.

In the parallel combination of resistance then the voltage remain same in the each part of the circuit.

Hence, In the series combination of resistance then the current remains same.
