Question

In the given circuit reading of ideal voltmeter is:-
(A) 2V
(B) 4V
(C) 6V
(D) 8V

[Hint: (D) is not the correct answer ]

Answer 1

Thus the voltage of ideal voltmeter is 4 V.

Explanation:

As we know that

Voltage = Current x Resistance

V = IR

Since the resistances are in series

V = 8 - IR1 - IR2 - IR3

V = 8 - 2 - 2

V = 8 - 4

V = 4 V

Thus the voltage of the ideal voltmeter is 4 V.

A voltmeter is an instrument that is used to measure the electric potential difference. Its S.I unit is Volt.

Answer 2

Answer:

A 2V

because the connection is in parallel
