In given figure the ammeter A reads 5 A and voltmeter V reads 40 V. The actual value of resistance R is

A

`8 Omega`

B

greater than `8 Omega`

C

less than `8 Omega`

D

`200 Omega`

Text Solution

Verified by Experts

The correct Answer is:
C
Combind resistance of R and ammeter`=8Omega`.
Now , `R_A +R=8 rArr R lt 8 Omega`.
