Question

An ideal voltmeter is connected in Fig. The current in circuit is

• A. 2A
• B. 2.5A
• C. Infinity
• D. zero

Answer 1

The correct option is D zero

In the given circuit ideal voltmeter is connected i.e. the resistance of voltmeter is infinity.
The current through the circuit is
$I=\frac{V}{R}$
$\Rightarrow I=\frac{5}{0.5+2+\infty }$
$\Rightarrow I=\frac{5}{\infty }=0A$
