The drain current in jfet is controlled by:
WebJunction field-effect transistor (JFET) JFET, as abbreviated, is a unipolar-transistor whose current can be controlled by an external applied voltage. It has three terminals referred to as: source, gate, and drain. Between the source and drain, there is a channel made of either n-type semiconductor (n-channel) or p-type semiconductor (n-channel). WebWhat is the no bias drain to source current of an n-channel JFET (Junction Field effect transistor) if its gate to source voltage is -3 Volts, pinch-off voltage is -1 volts and drain current is -24 miliampere? 5 mA 16 mA 3 mA 8 mA. …

WebJFET or Junction Field Effect Transistor is one of the simplest types of field-effect transistor. Contrary to the Bipolar Junction Transistor, JFETs are voltage-controlled devices. In JFET, the current flow is due to the majority of charge carriers. However, in BJTs, the current flow is due to both minority and majority charge carriers.
WebAug 20, 2024 · Remembering that the JFET is a voltage-controlled device, not a current-controlled device like the bipolar junction transistor.
