Find the current `I` & voltage `V` in the circuit shown.

Text Solution

Verified by Experts

The correct Answer is:
`I=2.5 A, V=3.5` Volts

resistance of circuit
`R_(eq)=(12||48)+0.4+(12||12)`
`R_(eq)=(12xx48)/(12+48)+0.4+(12xx12)/(12+12)`
`R_(eq)=16 Omega`
`I=(60-20)/16impliesI=2.5` Amp
`I_(1)=12/60xx2.5implies I_(1)=0.5 Omega`

Reading of voltmeters
`V=I_(1)xx7impliesV=0.5xx7`
`V=3.5` volt
