## Difference between Unilateral and Bi-Lateral Circuits & Elements

Unilateral circuits In unilateral circuits, the property of circuit changes with the change of direction of supply voltage or current. In other words, unilateral circuit allows the current to flow only in one direction. Diode rectifier is the best example of unilateral circuit because it does not perform the rectification in both direction of supply. Bi-lateral circuits In bilateral circuits, …

## The Main Difference between Linear and Nonlinear Circuit

The Main Difference between Linear and Nonlinear Circuit Linear Circuit In simple words, a linear circuit is an electric circuit in which circuit parameters (Resistance, inductance, capacitance, waveform, frequency etc) are constant. In other words, a circuit whose parameters are not changed with respect to Current and Voltage is called Linear Circuit. Fundamentally, the word “linear” literally means “along with …

## Ohm’s Law with simple explanation

Ohm’s Law The relationship between Current through and Voltage across a conductor was first discovered by a German scientist George Simon Ohm. This relationship is called Ohm’s Law and be stated as; The Current “I” flowing through a conductor is directly proportional to the potential difference i.e. Voltage “V” across its ends provided the physical conditions (i.e. temperature, strain, etc) do …
