How to Calculate Input resistance of the common emitter amplifier?
Input resistance of the common emitter amplifier calculator uses resistance_input = (1/Base resistance+1/Base resistance+1/Small-signal input resistance b/w base-emitter) to calculate the Input resistance, The input resistance of the common emitter amplifier formula is defined as the opposition offered to the flow of current in the base region of the electrical circuit. Input resistance and is denoted by Ri symbol.
How to calculate Input resistance of the common emitter amplifier using this online calculator? To use this online calculator for Input resistance of the common emitter amplifier, enter Base resistance (R_{B1}), Base resistance (R_{B2}) and Small-signal input resistance b/w base-emitter (r_{π}) and hit the calculate button. Here is how the Input resistance of the common emitter amplifier calculation can be explained with given input values -> 0.08 = (1/50+1/100+1/20).
