7 W

D

annot be calculated

Text Solution

Verified by Experts

The correct Answer is:
A
Current in the circuit,
`I = ( E _(n et))/( R _( n et)),` where `E _( n et) & R _(n et)` represents Rret net emf of the circuit and net resistance of the circuit respectively.
`implies I = ( 10 - 4)/( 6) = 1 A`
` therefore` Power consumed by battery
`P = V xx I ,` where V & I represents volage and current to the circuit.
`implies P = 1 xx 4 =4 W`
