AC Circuit Containing Resistance, Inductance and Capacitance Circuit (LCR in series) - When an AC source is connected in a circuit with a resistance and a reactance together, the current varies initially in a complex way. After sufficient time, a sinusoidally..

When an AC source is connected in a circuit with a resistance and a reactance together, the current varies initially in a complex way. After sufficient time, a sinusoidally varying current persists in the circuit. This steady state current has a frequency equal to that of ..

Let an AC source be connected across a pure inductive element. If the alternating current I = I o sin w t flows through it. Then According to Kirchhoff's Law E = E o cos w t or..

Mutual Inductance - We know that if a current builds up or varies in a coil, the flux change leads to induced e.m.f in the same coil. This can happen event mutually between two interacting coils are close together, and if current is passed in one of them, it sets up a magnetic flux surrou..

. The magnitude of the current depended on the strength of the magnet and also on the magnitude of their relative velocity. Similar results were seen when the magnet is replaced by as coil connected to a battery. Even without physically moving the coils a current was shown in the galvanometer only ..

. Other repeating coils, connecting other pairs of subscribers, may be tied in at the points BC, B'C', and when G, connected will offer extremely high impedance to the flow of voice current from one channel to the other, but practically none to the flow of voice current in its own channel. The talk..

Let an AC source be connected across pure inductive element. If E = E o sin w t then, q = EC = CE o sin w t I = I o cos w t Here I o = E o C w = E o C w plays the role of a resistance and is known as capacitive reactance X c ...

Q stands for quality. The voltage magnification produced by series resonance is termed as Q-factor of the series resonance circuit..

Average Power Associated with LCR Circuit in Series - In an electrical circuit, energy is supplied by the source of EMF, stored by the capacitive and inductive elements and dissipated in resistive elements. Conservation of energy requires that, at any particular time, ..

Electromagnetic induction (E.M.I) is the phenomenon of generating EMF by changing the number of magnetic lines of force associated with a circuit. The EMF so generated is called induced EMF and the corresponding current is called induced curren..
