Question

3 and 4th..............

Answer 1

Answer:3) ammeter reading=1A

voltmeter reading=2V

4) I'M NOT SURE

1)CURRENT drawn=6A

2)ENERGY=4.5*10^3

3)COST=6*10^-4

Explanation:

Answer 2

Explanation:

Reff in series=R1+R2

Reff=1+2

Reff=3 ohm

in series current is constant

V=IR

3=I×3

I=1Amp

calculating voltage in 2 ohm resisor

v=IR

V=1×2

v=2 ohm

1.reading in ammeter-1Amp

2.""" "" voltmeter is 2 ohm
