Question

In the figure shown hot wire voltmeter and hot wire ammeter are ideal. The reading of voltmeter is :-

Options

A.

5 $\sqrt{2}$ V

B.

5 V

C.

10 V

D.

None of these

Solution

$Z Â = \sqrt{(X_{L} - X_{C})^{2} + R^{2}} = \sqrt{25 + 25} = 5 \sqrt{2} I_{r m s} Â = \frac{10 / \sqrt{2}}{5 \sqrt{2}} = 1$
