GIVEN:
according to the given circuit:
resistance are connected in parallel.
So effective resistance is 1/R=1/R1+1/R2+1/R3
∴1/R=1/2+1/4+1/6
⇒11/12
∴r=12/11 ohms.
Voltmeter reading:
V=IR⇒11x12/11= 12 volts[∵i=11 amp]
Ammeter reading:
V=IR
I=V/R
=12/4
3 amp [∵R=3 ohms]
So voltmeter reading is 12volts and ammeter reading is 3amp
