Answer 1

Answer:

2 A

Explanation:

R total = 3+3+3 = 9 ohm.

V = 18 V

We know that in series same amount of current flows through each resistor. So,

I = V/R

I = 18/9

I = 2 A..

Hence, reading of Ammeter is 2 A

Hope it helps....!

Answer 2

Answer:

THE AMMETER IS ONLY CONNECTED TO A PARTICULAR RESISTANCE.

SO WE HAVE TO FIND CURRENT FLOWING THROUGH 3ohm RESISTANCE WITH POTENTIAL DIFFRENCE 18v.

$v = ir$

I=V\R

Í= 18/3

I = 6 AMPERE
