The resistive network shown below is connected to a D.C. source of 16V. The power consumed by the network is 4 Watt. The value of R (in `Omega`) is _______.

A

`8 Omega`

B

`6 Omega`

C

`1 Omega`

D

`16 Omega`

Text Solution

Verified by Experts

The correct Answer is:
A
`R_(eq) = V^(2)/P = 16^(2)/4 = 64 Omega`
`2R + R + 4R + R = 64 rArr 8R = 64 rArr R = 8 Omega`
