What is the reading of the Voltmeter shown in the figure? a. 8V

b. 10V

c. 16V

d. 20V

Correct option is A)

Let us assume voltmeter is ideal:-It means voltmeter has infinite resistance and current will not flow in voltmeter.

R

eq

in upper branch = R

eq

in lower branch. So current will get equally divide into both branches.

V

A

−V

B

=4×1(1)

V

A

−V

D

=16×1(2)

Subtract 2 and 1

V

B

−V

D

=12V

A voltmeter will read 12 V

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.

it is easily magnetized.
