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. Even approaching the burnout current value without reaching it can shorten its life. Therefore manufacturer's data sheet specifies the maximum forward current, that diode can withstand. This average current IF is the rate a diode can handle up to the forward direction when used a...
