Actually it can be used as a diode, but rarely is. Just connect the grid and plate together and it has been reduced to a diode. There are also certain circuits that use the cathode and grid as a diode, while also obtaining an amplified output on the plate.

Can the two end of a center tap transformer be use with out a rectifier?

The twoends of a center tap transformer cannot be used without a rectifier.


What is the advantage of triode?

With a diode tube you have no control over the current flow and it can only be used as a rectifier, where the triode consist of a control grid, to control the flow of electrons that will reach the anode, this make it possible to use the triode as a amplifier, compared to a transistor the control grid have the same function as the base of the transistor.Advantages?Over tetrodes and pentodes:1. Operation at higher radio frequencies,2. Lower noise figures,3. Simpler circuitry and only one power supply.


What is the effect of inductive load on a single phase full wave bridge rectifier?

rectifier is used to resist the current likewise in bridge wave rectifier ,the inductive load is used to resist high amount of current because in bridge wave we cannot resist the current by using rectifier ..so we are using inductive load here


Can diode be used as rectifier?

yes ofcourse diode can be used as rectifier but it's an uncontrolled rectification.


What is single phase Controlled rectifier?

such a control rectifier that control or rectifier single phase. for that purpose we used SCR that is called single phase controlled rectifier.


Can a diode be used as rectifier diode?

yes, diode can be used as rectifier diode to convert ac to dc


What is use of rectifier?

Rectifier is used to convert alternating current to direct current.


What is another name for rectifier convert dc to radio waves ac?

You cannot use a rectifier to go from DC to AC. You need an oscillator.


Why you use tetrode instead of triode?

a tetrode is used when you need a screen grid tube, but a suppressor grid tube can't be used.OK, but the question was "why use a tetrode instead of a triode?"So, the answer...1. A tetrode has a higher voltage/power gain than a triode.2. A tetrode has less anode-grid feedback capacitance than a triode, and can operate in common-cathode radio frequency circuits without the neutralisation (or other corrective circuitry) that is needed by a triode.


What is phase control?

such a control rectifier that control or rectifier single phase. for that purpose we used SCR that is called single phase controlled rectifier.


Which rectifier is not directly operated from mains?

Because , the high voltage can destroy the diodes used in the rectifier .


How can we Diode can be used as a rectifier?

A diode is used to stop the negative voltage swing in an AC signal, so you only get the positive portions.diode-rectifier
