When an AC source is connected to a capacitor there is a steady-state current in the circuit. Does it mean that the charges jump from one plate to the other to complete the circuit?

An AC source is connected to a capacitor. Will the rms current increase, decrease or remain constant if a dielectric slab is inserted into the capacitor?

When the frequency of the AC source in an LCR circuit equals the resonant frequency, the reactance of the circuit is zero. Does it mean that there is no current through the inductor or the capacitor?

A battery of emf 10Vand internal resistance 3 Omega is connected to a resistor.If the current in the circuit is 0.5A, what is the resistance of the resistor ? What is the terminal voltage ot the battery when the circuit is clossed ?

An inductor coil joined to a 6 V battery draws a steady current of 12 A . This coil is connected to a capacitor and an AC source of rms voltage 6 V in series. If the current in the circuit is in phase with the emf, find the rms current.

If an LCR series circuit is connected to an ac source, then at resonance the voltage across

A constant current exists in an inductor coil connected to a battery. The coil is short circuited and the battery is removed. Show that the charge flown through the coil after the short circuiting is the same as that which flows in one time constant before the short circuiting.

A capacitor is connected to an alternating- current source. Is there a magnetic field between the plates ?

A 44mH inductor is connected to 220V, 50 Hz ac supply . Determine the rms value of the current in the circuit .

A battery of emf 10 V and internal resistance 3Omega is connected to a resistor. The current in the circuit is 0.5A. The terminal voltage of the battery when the circuit is closed is
