In the circuit shown, the battery, the ammeter and the voltmeter are ideal. Pick the correct choice(s) :

A

Power supplied by battery is 72 W

B

Rate of heat dissipation in `3Omega` resistance is 12 W

C

The ammeter reads `4/3A`

D

The voltmeter reads 22 V

The lower network of 4-8-6-2-4 is a wheat stone bridge in balanced condition since So, we remove . Now, net resistance in series with battery is `6Omega`
`implies` Current through battery=4V
So, current in the three branches, starting from the top are `2A,2/3A,4/3A`
`implies` Ammeter reads `2/3A`, Voltmeter reading =24-(L) (2)
`implies` Power supplied `=24 times 4=96W implies` Dissipation in `3Omega=2^2 times 3=12W`
