A choke coil is preferred to a rheostate in AC circuit as

A choke coil is preferred to a resistance for reducing current in an ac circuit because .

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 choke coil and capacitor are connected in series and the current through the combination is maximum for AC of frequency n. If they are connected in parallel, at what frequency is the current through the combination minimum?

A capacitor of capacitance 250 pF is connected in parallel with a choke coil having inductance of 1.6 xx 10^(-2) H and resistance 20 Omega . Calculate (a) the resonance frequency and (b) the circuit impedance at resonance.

A bulb is rated at 100V, 100W. It can be treated as a resistor. Find out the inductance of an inductor (called choke coil) that should be connected in series with the bulb at its rated power with the help of an ac source of 200V and 50Hz.

The power factor of a good choke coil is

In the steady state condition the rate of heat produced in a choke coil is P . The time constant of the choke coil is tau . If now the choke coil is short circuited, then the total head dissipated in the coil is

A : For a practicval choke coil the power factor is very small. R : In a practical choke coil the power dissipation reduces if frequency of the a.c. is increased.
