Definition of "Forward Bias" |
A dc voltage applied to a pN junction semiconductor so that the positive terminal of the voltage source connects to the p-type material and the negative terminal to the N-type material. It produces forward current in the circuit. / An external voltage that is applied to a PN junction in the conducting direction so that the junction offers only minimum resistance to the flow of current. Conduction is accomplished by majority current carriers (holes in P-type material; electrons in N-type material). Refer to the graph to the right. The bias which tends to produce current flow in the forward direction Forward Resistance. The smaller resistance value observed when you are checking the resistance of a semiconductor. / A dc voltage applied to a pN junction semiconductor so that the positive terminal of the voltage source connects to the p type material and the negative terminal to the N type material. It produces forward current in the circuit. / a PN junction bias which allows current to flow through the junction. Forward bias decreases the resistance of the depletion layer. |
