What is a unilateral element ?
Think about a simple diode, which is connected with a voltage source. If somehow the polarity is changed, that is the (+) & (−) terminal interchanged, then the diode will not work. So, we can say, diode is an unilateral element. A important feature of an unilateral element is, it offer varying impedances with variations in flow of current.
Basically, semiconductor devices like diodes, transistors, operational amplifiers are the unilateral element.
Suppose, an electrical element is connected with a voltage source. If the element is unilateral, then whenever there is a change is occurred in the polarity of the applied voltage, that is the positive & negative terminal of the source altered, the magnitude of the current passing through the element is affected by the polarity change.
