Question

What does bias mean?

Answer 1

Hint: In a transistor, bias refers to the direction in which direct current travels from the emitter to the base. Similarly, bias refers to the direction of current flow between the base and the collector. Certain bias conditions are employed for a specific reason.

Complete step by step solution:
A diode is said to be forward biassed if its P-side is linked to the positive terminal of the battery and its N-side is connected to the negative terminal. In reverse bias, the p-side is linked to the battery's negative, and the n-side is connected to the n-side. Biassing is generally described as a configuration created in a diode or an electrical device to allow a greater flow of current in a specific direction. A gadget, or more properly a diode, can be coupled to a source in a variety of ways. One technique uses forward bias, which acts like a closed switch and allows current to pass through it. Furthermore, a device is said to be forward biassed when the anode is linked to the positive end of the battery, and the cathode is attached to the negative end. Forward bias, also known as biassing, is the application of an external voltage across a P-N junction diode. In a forward bias configuration, the P-side of the diode is connected to the positive terminal, and the N-side is connected to the negative terminal of the battery.
Note: In this case, the applied voltage is opposed to the junction barrier potential. As a result, the effective potential barrier and junction width drop, resulting in more carriers flowing over the junction. The bulk of charge carriers must travel across a forwards biased PN junction. The breadth of the depletion layer has shrunk.
