![]() When the input voltage is applied at the base terminal, then some amount of current starts to flow from the base terminal to the emitter terminal and controls the current at the collector terminal. ![]() In reverse bias mode, this transistor doesn’t allow the flow of current through the collector & emitter. When we will do not apply any voltage (or apply negative voltage) at the base terminal of this transistor, then it starts working as Reverse Bias. In forward bias mode, this transistor allows the flow of current through the collector & emitter. So, when we will apply positive voltage at the base terminal of this transistor, then it starts working as Forward Bias. This transistor has two working states, one is Forward Bias and another one is Reverse Bias.īC547 is an NPN transistor. The current supplies out through the emitter terminal. This pin controls the transistor biasing. ![]() The flow of current will be through the collector terminal.
