Variables Used
Output Voltage - (Measured in Volt) - The Output Voltage is the voltage detected at the end of the transistor.
Transconductance - (Measured in Siemens) - Transconductance in small signal amplifiers refers to the change in current output for a small change in input voltage. It is a measure of the amplifier's ability to follow small signal variations.
Critical Voltage - (Measured in Volt) - Critical Voltage is the minimum phase to the neutral voltage which glows and appears all along the line conductor.
Source Resistance - Source Resistance is the amount of resistance applied at the source terminal of the transistor.
Small Signal Resistance - (Measured in Ohm) - The small signal resistance is a measure of the opposition to the flow of small signals in an electronic circuit.
