In a $L CR$ oscillatory circuit, find the energy stored in inductor at resonance if voltage of source is $10 V$ , resistance is $10Ω$ and inductance $= 1 H$ .

Options:

Answer:

Solution:

At resonance, current $I = \frac{V}{Z _{m i n}} = \frac{V}{R} = \frac{10}{10} = 1 A$ Energy of inductor $= \frac{1}{2} L I^{2} = \frac{1}{2} (1) (1)^{2} = 0.5 J$
