Ticket No1 1)The characteristic is called output characteristic or volt-ampere charateristic of a Rectifier Diode. 2)Rectifier Diode. 3) A is called Anode and C is called Cathode. An Anode has positive potential and therefore collects electrons in the device. Cathode has negative potential and therefore emits electrons to anode. The symbol looks like an arrow that ponts from the anode to the cathode, and reminds that conventional current flows easily from the p side(anode) to the n side(cathode). BIASING. Forward biasing. If the current in a diode is too large, excessive heat will destroy the device.
