the big advantage is they are very low cost
the big disadvantage is they can't be turned OFF

What is designed to use a small current to control a large current?
A silicon controlled rectifier falls into this category.
What is SCR in drilling rig?
It is a silicon-controlled rectifier, converting AC to DC for use in drawworks, mud pumps, etc.:silicon-controlled-rectifier
Why the bridge rectifier is best?
What is the advantage of using the bridge rectifier A: NONE no advantage the only advantage can be considered it the fact it will provide more voltage but never more power actually less by a .7 volt diode drop
Difference between silicon-controlled rectifier and diode?
silicon controlled rectifier is a 3 terminal 4 layer device which has 2 consecutive P N junctions here the three terminals called anode, cathode and gate gate controls the conduction of the scr but diode just conducts in forward bias and blocks in reverse bias
Why Silicon Controlled Rectifier is called current controlled device?
Because it is controlled by the gate current
The conclusion of a silicon controlled rectifier?
conclusion of silicon control rectifier
What is designed to use a small current to control a large current?
A silicon controlled rectifier falls into this category.
What is SCR Give its application?
scr is a silicon control rectifier used to control the rectifing voltage.. its a bidirectional device can use it for both the directions......
What are the advantages of a silicon-controlled rectifier?
SILICON CONTROLLED RECTIFIER APPLICATIONS i) Speed control for motors ii) Temperature control for electric hot plate iii) Dimmer switch for domestic lighting iv) Dimmer control for stage lighting.
What is SCR in drilling rig?
It is a silicon-controlled rectifier, converting AC to DC for use in drawworks, mud pumps, etc.:silicon-controlled-rectifier
Why it is named silicon controlled rectifier?
i got no idea mate
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.
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.
Why the bridge rectifier is best?
What is the advantage of using the bridge rectifier A: NONE no advantage the only advantage can be considered it the fact it will provide more voltage but never more power actually less by a .7 volt diode drop
When an SCR turns on it acts like n?
An SCR (Silicon Controlled Rectifier) acts like a switch when turned on. It can also be used as a rectifier.
When An SCR conducts appreciable current?
And SCR will conduct appreciable current when it is gated "on" and thus "told" to conduct. A silicon controlled rectifier(SCR) is an electronically controlled DC switch, and the gate is the terminal to which the control voltage is applied. Use the link below to learn more.
Why silicon controlled rectifier doesn't work in reverse biased condition?
Because when reverse biased it behaves like any other rectifier/diode.
