Nyquist plot is a graphical representation of a system's frequency response in the complex plane.

• Nyquist plot shows how a system responds to sinusoidal inputs at different frequencies.

• It plots the real part of the transfer function against the imaginary part.

• The plot can help analyze stability and performance of control systems.

• A Nyquist plot can be used to determine the stability of a system by looking at the encircle...read more

Ohm's law states that the current flowing through a conductor is directly proportional to the voltage across it, and inversely proportional to the resistance of the conductor.

• Ohm's law is represented by the formula V = I * R, where V is voltage, I is current, and R is resistance.

• It helps in understanding the relationship between voltage, current, and resistance in an electrical circuit.

• It is named after the German phys...read more
