PhysicsHardsingle choice

An inductive circuit contains a resistance of $10Ω$ and an inductance of $2.0 H$ . Ifan $AC$ voltage of $120 V$ and frequency of $60 Hz$ is applied to this circuit, the current in the circuit would be nearly

Options:

Answer:

Solution:

Here, impedence $z = R^{2} + X_{L}^{2}$ $∴ (10)^{2} + (2 π \times 60 \times 2)^{2} = 753.7$ $∴$ Current $i = \frac{V}{Z} = \frac{120}{753.7} = 0.159 A$
