Question

In the circuit shown, the reading of the voltmeter is :
(Assume voltmeter to be ideal)

(A)125 V
(B)105 V
(C)6 V
(D)18 V​

Answer 1

Answer:

equilent resistance = 1600/3

series ma current euual ha

I=24÷{1600/3)

=9/200

V=9/200×400= 18

Answer 2

Answer:

Option D is correct

Explanation:

first we need to find equivalent resistance of three resistors

1/R = 1/200 + 1/400

1/R = 3/400

R = 400/3

:- now third resistor is in series

R = 400/3 + 400

R= 1600/3

Now we need to find out current:-

V=IR

24=1600/3 × I

72/1600 = I

0.045 = I

• we have current and equivalent resistance

V=IR

V= 0.045×400

V=18V
