Alternating Current

Also in 2022

A series LCR circuit with inductance 10 H, capacitance 10 $\mu$ F, resistance 50 $\Omega$ is connected to an ac source of voltage, V =200 sin(100 t)volt. If the resonant frequency of the LCR circuit is $v_{0}$ and the frequency of the ac source is v, then:

Other years

To an ac power supply of 220 V at 50 Hz, a resistor of 20 Ω, a capacitor of reactance 25 Ω and an inductor of reactance 45 Ω are connected in series. The corresponding current in the circuit and the phase angle between the current and the voltage is, respectively

In an ideal transformer, the turns ratio is $\frac{N_p}{N_s}$ = $\frac{1}{2}$ . The ratio $V_s$ : $V_p$ is equal to (the symbols carry their usual meaning):

In a series LCR circuit, the inductance L is 10 mH, capacitance C is 1 $\mu$ F and resistance R is 100 $\Omega$ . The frequency at which resonance occurs is:
