Question

Two resistors of 2 ohm and 3 ohm are connected in series. The potential different of 2 ohm
resistor is 0.40 V. The potential difference at the ends of resistor of 3 ohm will be
(a) 0.40 V
(b) more than 0.40 V
(c) less than 0.40 V
(d) none of these​

Answer 1

Answer:

Answer is = [b] More than 0.40V

Explanation:

We know that current in Series connection is same.

Therefore, From V= IR

0.40 = I × 2 ( Ist Resistor)

I = 0.40/2

I = 0.2 A

Since, Current is same in each case.

Hence, Again from V= IR

V= 0.2 × 3 ( 2nd Resistor)

V= 0.6V
