Question

2.
In the circuit shown in figure, the reading of the voltmeter V will be:
​

Answer 1

Answer:

(a) 4 V

Explanation:

voltage across the voltmeter will be same as voltage across 100ohm resistor as they are connected in parallel and in parallel voltage remains same in each branch .

sowe have

I total= V/R

I = 12/100+200

I = 0.04 A

so voltage across 100ohm resistor as well as The VOLTMETER is V=I*R

V=0.04*100

V=4 V
