In Figure E6-1, which is the schematic symbol for a P-channel junction FET?

Explication

Symbol 1 shows one gate joining an unbroken channel line, which marks a junction FET rather than an insulated-gate device, and its gate arrow points outward from the channel toward the gate lead — the P-channel marking. Symbol 6 is the N-channel JFET with that arrow reversed, and symbols 2 and 3 are single-gate MOSFETs with the gate drawn separated from the channel.
