current electricity rc series circuit rc dc transient circuit growth and decay of charge class 12

The resonance frequency of a certain RLC series circuit is omega_(0) . A source of angular frequency 2 omega_(0) is inserted into the circuit. After transients die out, the angular frequency of current oscillation is

Assertion : At resonance, LCR series circuit have a minimum current. Reason : At resonance, in LCR series circuit, the current and e.m.f. are not in phase with each other.

The electric current through 10 ohm resistor in circuit given below is

What is meant by electric circuit ? Why does electric current start flowing in a circuit the moment circuit is complete ? When do we say that the potential difference across a conductor in a circuit is 1 volt ? Calculate the potential difference between the two terminals of a battery if 12 joules of work is done in transferring 2 coulombs of charge.

In the given circuit diagram when the current reaches steady state in the circuit, the charge on the capacitor of capacitance C will be:-

A dc ammeter and a hot wire ammeter are connected to a circuit in series. When a direct current is passed through circuit, the dc ammeter shows 6 A. When ac current flows through circuit, the ac ammeter shows 8A. What will be reading of each ammeter if dc and ac current flow simulataneously through the circuit?

If the capacitor shown in the circuit is charged to 5V and left in the circuit, in 12s the charge on the capacitor will become:

An AC source of frequency omega when fed into a RC series circuit, current is recorded to be l. If now frequency is changed to (omega)/(4) (keeping voltage same), the current is found to 1/2. The ratio of reactance to resistance at original frequency omega is

A resistor and a capacitor are connected to an ac supply of 200 V, 50 Hz, in series. The current in the circuit is 2A. If the power consumed in the circuit is 100 W then the resistance in the circuit is
