In the circuit shon below , the ammeter and the voltmeter readings are 3 A and 6 V respectively . Then the value of the resistance R is

A

` gt 2 Omega `

B

` ge 2 Omega `

C

`2 Omega`

D

`lt 2 Omega `

Text Solution

Verified by Experts

The correct Answer is:
D
Case I : If ammeter A and voltmeter V are
ideal , then `R = (6A)/(3A) = 2Omega `
Case : II If ammeter A and voltmeter V has some finite resistance, then `R lt 2 Omega `
