Assetion : In the following circuit emf is `2 V` and internal resistance of the cell is `1 Omega` and `R = 1 Omega`, then reading of the voltmeter is `1 V`.
Reason : `V = E - ir` where `E = 2 v, i= (2)/(2) = 1 A` and `R = 1 Omega`

A

If both the assertion and reason are true and reason is a true explanation of the assertion.

B

If both the assertion and reason are true but the reason is not the correct explanation of assertion.

C

If the assertion and reason are false

D

If both the assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
A
(a) Here, `E = 2 V, 1 = 2//2 = 1 A` and `r = 1 Omega`
Therefore, `V = E - ir = 2 - 1 xx 1 = 1 V`
