Answer #1

In electromagnetism, inductance is the tendency of a conductor to oppose a change in the electric current flowing through it.

The origin of inductance is electromotive force to be generated by a change in the current flowing.

Impedance is the measure of the opposition that a circuit presents to a current when a voltage is applied. Impedance is a combined effect of resistance and reactance.

The inductor and capacitor can be connected in parallel or series based on the application we are using.

The impedance of inductor is  jwL

Where w = frequency and L is the inductance.

The impedance of capacitor is 1/jwC.

Where C is the capacitance.
