What Is Forward Bias

The term biasing refers to the electrical supply or the potential difference associated with a semiconductor diode.

Forward bias and reverse bias.

The two primary types of bias include forward bias and reverse bias.

  • Forward bias involves a reduction in the potential barrier of the semiconductor diode, and it also involves the establishment of an easy path for the flow of current.
  • Reverse bias involves an increase in the strength of the potential barrier, which results in the prevention of the charge carrier’s movement across the junction diode.
  • It is important to note that reverse bias generally provides a highly resistive path for the current flow and is generally accompanied by no current flowing through the circuit.
  • The battery’s positive terminal is connected to the P-type semiconductor of the device, and the negative terminal is connected to the N-type semiconductor in forwarding bias.
  • In reverse biasing, the battery’s negative terminal is connected to the P-region, and the positive terminal of the battery is connected to an N-type semiconductor.
