Draw the V-I characterisitics of p-n junction diode in forward bias and in reverse bias. |
Answer» Solution :In a p-n junction , forward biasing is applied by connecting +ve of the battery to p-section and -ve of the battery of n-section. In the CASE of REVERSE biasing, +ve of the battery is connected to n-section and -ve of the battery is connected to p-section . As a result, the strength of the current CARRIERS moving in the circuit will  change. It can be used by taking the arrangement to use it as half or full wave rectifier or in any other form. A graph between voltage and current for forward bias and reverse bias is as shown in the fig. From the fig., we find that during forward bias, the p-n junction offers less resistanceand during reverse bias it offers LARGE resistance. |
