In an AC circuit the emf `(e)` and the current `(i)` at any instant are given respectively by, `e =E_0 sin omega t and i = I_0 sin (omegat-phi)` The average power in the circuit over one cycle of AC
L-C Oscillations When a capacitor is supplied with an AC circuit, it gets charged.When this charged capacitor is connected with an inductor, current flows through inductor, giving rise to magnetic flux. Hence, induced emf is produced in the circuit. Due to this, the charge on the capacitor decreases and an equivalent amount of energy is stored in the inductor in the form of magnetic Field.The physical quantity that has same dimension as that of `sqrt(LC)`
Assertion: If an inductor coil is connected to DC source, the current supplied by it is `I_1`.If the same coil is connected with an AC source of same voltage. Then, current is `I_2`. Then, `I_2 < I_1.` Reason: In AC circuit, inductor coil offers more
Assertion: Average power in an AC circuit is given by `P=I_(rms)^2 R` . Reason: In one full cycle, net power is dissipated not only in a
Assertion: Average value of current in half the cycle of an AC circuit cannot be zero. Reason: For positive half cycle average value of current is `(i_0)/pi`, where `i_0` is the peak value
