WebTo draw I-V characteristic curve: When a p-n junction is in forward bias, current flows through the junction from the p-side to the n-side. The forward bias voltage creates a potential difference across the junction, which allows electrons to flow from the n-side to the p-side. The net result is a small current flowing through the junction. WebPN Junction Bias. In Figure below (a) the battery is arranged so that the negative terminal supplies electrons to the N-type material. These electrons diffuse toward the junction. … WebThe term bias refers to the application of DC voltage to set up certain operating conditions.
