![]() ![]() The negative terminal of the battery is connected to the P-region and the positive terminal of the battery is connected to N-type semiconductor. The positive terminal of the battery is connected to the P-type semiconductor of the device and the negative terminal is connected to N-type semiconductor The external voltage which is applied to the PN junction for strengthening the potential barrier and prevents the flow of current through it is called reverse bias. The external voltage which is applied across the PN-diode for reducing the potential barrier to constitutes the easy flow of current through it is called forward bias. ![]() Content: Forward Biasing Vs Reverse Biasing The reverse bias provides the high resistive path to the flow of current, and hence no current flows through the circuit. While in reverse bias the potential difference increases the strength of the barrier which prevents the charge carrier to move across the junction. ![]() The forward bias reduces the potential barrier of the diode and establishes the easy path for the flow of current. The potential difference is of two types namely – forward bias and the reverse bias. Biasing means the electrical supply or potential difference is connected to the semiconductor device. ![]()
