PhysicsEasysingle choice

In a series LCR circuit the rms voltages across the inductance, capacitance and resistance are respectively $4 V$ , $8 V$ and $5 V$ . The RMS voltage of the AC source in the circuit is

Options:

Answer:

Solution:

Given $V_{L} = 4 V, V_{C} = 8 V, V_{R} = 5 V$
Using $V = \sqrt{V_{R}^{2} + {(V_{C} ~ V_{L})}^{2}}$

$= \sqrt{5^{2} + {(8 - 4)}^{2}} = \sqrt{41}$

$= 6.4 V$
