PhysicsEasysingle choice

An LCR series circuit is connected to an oscillator (AC supply) having RMS voltage $200 V$ . If the RMS voltages across resistor, inductor and capacitor are equal, then RMS voltage across the resistor would be

Options:

Answer:

Solution:

$∵ V = \sqrt{{V_{R}}^{2} + {(V_{L} - V_{C})}^{2}} = V_{R} (∵ V_{L} = V_{C})$

$V_{R} = V = 200 v o l t$
