The resistive network shown below is connected to a D.C. source of 16 V. The power consumed by the network is 4 Watt. The value of R is:
  1. 16 Ω
  2. 8 Ω
  3. 6 Ω
  4. 1 Ω

Solution

Req for mixed series and parallel combination of

  given circuit Req=114R+14R+R+116R+112R+R

Req=8R
Power dissipated by circuit P=V2Req
⇒4=1628R
⇒R=25632=8 Ω
