A diode is a semiconductor device with 2 electrodes : anode and cathode.
A diode is a semiconductor device which allows current flow in one direction only. It is made from a single piece of semiconductor which is doped n-type and the other p-type.
A diode conducts only when it is forward biased. (anode is made more positive compared to cathode). Under forward bias, current flows.
A diode does not conduct when reverse biased. (cathode is made more positive compared to anode). Under reverse bias, there is no current in the circuit.
Reflect on this :
Is there an analogy between the diode and the hydraulic valve in the picture below?
Hint:Fig (a) shows a forward biased diode and fig (b) shows a reverse biased diode
There is an analogy between the diode & the hydraulic valve. The analogy is the flow permitted to control the hydraulic check valve.
ReplyDelete(a) the valve is open. (b) the valve is closed.
ReplyDeleteIn Figure B The current Doesn't pass
ReplyDeleteAnd in the figure A is passing
A diode is a semiconductor device with 2 electrodes : anode(a)and cathode(k).

yes,because both of them allow the flowed for one direction
ReplyDeleteYes, because both of them can let the flow pass in one direction

In hydraulics is a switch .. but the electric will not make the current wont flow
