Question

13. In the circuit shown below, the ammeter and the voltmeter
readings are 3 A and 6 V respectively. Then the value of the
resistance R is
R
[KCET 2015]
(a) > 222
(c) 222
(b) 2 222
(d) <222​

Answer 1

i=3 v=6

r=v/i

r=6/3

r=2

therefore r is 2

Answer 2

Answer:

D

Explanation:

if voltmeter and ammeter are ideal only then R=V/I=2 ohm . Otherwise if voltmeter and ammeter both have finite resistance then R is less than 2 ohm
