In an $A C$ circuit the potential differences across an inductance and resistance joined in series are respectively $16 V$ and $20 V$ . The total potential difference of the source is

Options:

Answer:

Solution:

$V_{L} = 16 V, V_{R} = 20 V$ . In the inductor the current lags by $\frac{π}{2}$ .
$∴ V = V_{L}^{2} + V_{R}^{2} = 256 + 400 ∴ V_{total} = 25.6 V .$
