Triode bias voltage calculator

Bias voltage refers to the voltage that should be set between the base-emitter and the collector-base when the transistor is in the amplification state in the transistor amplification circuit. For the transistor to be amplified, the PN junction between the base and the emitter should be positively biased, and the PN between the collector and the base should be inversely biased.
