UNILATERAL AND BILATERAL ELEMENTS

Unilateral elements:

The elements which offers different impedance's when voltage and current direction and polarities are changed are known as Unilateral elements

Unilateral

• Here we can see that Z(1) and Z(2)  are not the same when voltage and currents are changed.

Bilateral elements:

The elements which offers same impedance's when the direction and polarity of impedance's are changed

Bilateral

• Here both Z(1) and Z(2) remained the same even if the direction and polarities of voltage and current are changed.
