Q.Write the symbol of p-channel JFET.

The schematic symbol of a JFET is drawn as a vertical line representing the channel, with the drain (D) at the top, the source (S) at the bottom, and a horizontal gate (G) lead entering from the side. The quick visual test that separates the two types is the direction of the gate arrowhead.

• n-channel JFET: the gate arrowhead points towards (into) the channel line. This represents the p-type gate diffused onto an n-type channel.
• p-channel JFET: the gate arrowhead points away (outward) from the channel line — the opposite of the n-channel symbol.

A simple way to remember it: for the n-channel the arrow points inwards. Everything else about the two symbols is identical; only the arrow direction changes. …
