A resistance is connected to an `AC` source. If a capacitor is included in the series circuit, will the average power absorbed by the resistance increase or decrease? If an inductor of small inductance is also included in the series circuit, will the average power absorbed increase or decrease further?

A resistance is connected to a n AC source. If a capacitor is induced in the series cirucit, the average power absorbed by the resistance

A series RLC circuit is connected to an ac generator. The instant at which current in the circuit is zero, the energy stored in the capacitor and inductor are:

A resistance R draws power P when connected to an AC source. If an inductance is now placed in series with the resistance, such that the impedence of the circuit becomes Z , the power drawn will be

An AC source rated 100 V (rms) supplies a current of 10 A(rms) to a circuit. The average power delivered by the source

A coil of self-inductance L is connected in series with a bulb B and an AC source. Brightness of the bulb decreases when

An inductance and a resistance are connected in series with an AC potential . In this circuit

In a LCR series resonating circuit. Give the value of average power loss.

A choke coil is connected to an AC source. Some power is dissipated in coil. Now a capacitor is connected in series with the coil and source is same, then average power dissipated in the circuit does not changes. If ratio of inductive reactance of coil and capacitive reactance of capacitor is 1/x then find x

A resistance is connected to a capacitor in AC are the phase differece is (pi)/(4) between current and voltage. Whe the same resistance is connected to an inductor, phase difference becomes tan^(-1)(2) . Power factor of the circuit when both capacitor and inductor are connect to the resistance will be

A student in a lab took a coil and connected it to a 12 VDC source. He measures the steady state current in the circuit to be 4 A . He then replaced the 12 VDC source by a 12V,(omega=50rad//s)AC source and observes that the reading in the AC ammeter is 2.4 A . He then decides to connect a 2500 muF capacitor in series with the coil and calculate the average power developed in the circuit. Further he also decides to study the variation in current in the circuit (with the capacitor and the battery in series). The value of resistance of the coil calculated by the student is
