2.In the circuit shown in figure, the reading of the voltmeter V will be:
Answered by admin @
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
