Diodes and Applications

Q1: The arrow in the schematic symbol of a diode points to

A the n-type material, which is called the anode

B the n-type material, which is called the cathode

C the p-type material, which is called the anode

D the p-type material, which is called the cathode

ANS:C - the p-type material, which is called the anode

Here points mean define or represent not direction so;

Bar points(represent) - N type(-) lower potential or cathode.

Arrow points (represent)-P type(+) higher potential or anode.
And current always flows from (+)or higher potential to (-) or lower potential i.e Anode to cathode.
