PhysicsEasy94×since 2002Q5908In a series LRL RLR circuit XL=RX_{L}=RXL=R and power factor of the circuit is P1P_{1}P1. When capacitor with capacitance CCC such that XL=XCX_{L}=X_{C}XL=XC is put in series, the power factor becomes P2P_{2}P2. The ratio P1P2\frac{P_{1}}{P_{2}}P2P1 is:A12\frac{1}{2}21B12\frac{1}{\sqrt{2}}21C32\frac{\sqrt{3}}{\sqrt{2}}23D2 : 1Check answerSkip
