A valve allows flow in only one direction. Diodes allow electrical current to flow in one direction only.

What is diode volve?

I think you mean 'diode valve'! A 'valve' is the British term for what Americans call 'tubes' or, more accurately, 'vacuum tubes'. So, a 'diode valve' is a thermionic valve generally used as a rectifier, much in the same way that a semiconducting diode is used, these days.

What is the direction of current flow in a diode valve?

Inside the diode valve the conventional curret flow is from anode to cathode. The electron flow is from cathode to anode.


Why diode can't use as amplifier?

A2. For amplification to take place, one needs three terminals; an input, an output, and a control signal.This indicates the original " valve" naming; after a mechanical valve, where a small effort on a (hydraulic) valve may be used to control a larger effort of the controlled fluid.A1. If u meant why diode can't be used as an amplifier diode is used as a rectifier..it converts ac current to dc and there is an inbuilt voltage drop... so it can't be used as an amplifier


What is an equivalent diode of a triode valve?

Hard to answer this one.The triode is a diode with a control electrode (the grid) added.The only useful answer is that a triode is a voltage-controlled doide.Try asking the question so that it can be answered more usefully.


What does valve mean?

A valve in the Plumbing sense is a mechanical device to open or close the water flow. It can be a screw operation called a 'Gate Valve' or a simple 1/4 turn handle called a 'Ball Valve' . These are more modern and efficient.


What is impatt diode?

The read type diode are called impatt diode


Why is a kink provided for a glass diode on the PCB?

To provide relief for any mechanical stress on the diode, which might otherwise shater.


Why is a diode called bidirectional?

Its not, a diode is unidirectional.


What are the two leads on a diode called?

The two leads on a diode are called the anode and the cathode.


What is the freewheeling diode operation?

Very often in translations from German to English the term 'free wheeling diode' for 'Freilauf-Diode' is used. Generally the correct translation for this term would be 'recovery diode'. The usage of the term 'free wheeling' only will be correct in mechanical aspects, e.g. the rear wheel of a bicycle or the clutch of the transmission line of a car.


What is the purpose is of a diode?

The purpose of a diode is to allow electric current to pass in one direction while blocking electric current in the opposite direction. It is for this reason that diode is usually referred as the check valve.
