What else can I help you with?
Why scr is called as bidirectional an controlled device?
Because it can control input voltage in both halves of cycle.
Why scr is used as a rectifier?
it conducts in only one direction. it can also be used as a switch and made to not conduct at all.
An scr is an electronic device that?
That is used as a switching device. They are very common in Inverter circuits and can switch up to 1000's of amps.
What is the basic function of the SCR's gate electrode?
The SCR's gate electrode is used to turn the SCR on, i.e. fire it.
What does a thyristor works as a circuit breaker?
A thyristor is a type of semi-conductor and is used in a circuit to control the application of electrical power to a load. They are often found as the switching element in light dimmers and can be used as control elements in power supplies (variable or regulated). Types of thyristors are diacs, triacs, sidacs and SCRs (silicon controlled rectifier).
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......
Why SCR cannot be used as bidirectional device?
A SCR's (Silicon Controller Rectifier) name hints at the answer. As a rectifier (diode) current can only pass in one direction. There are devices at can pass in both directions, and typically they are a pair of SCR's wired in opposite polarity.
Why scr is called as bidirectional an controlled device?
Because it can control input voltage in both halves of cycle.
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.
Is SCR is a switch?
I's a electronic component that act like a controlled diode. It can be used as a switch on some applications, but with some limits. 1- A SCR is a diode, and as such, it only conduct in one direction. 2-The SCR only turn off when the current passing it reaches zero.

it conducts in only one direction. it can also be used as a switch and made to not conduct at all.

Contrast the scr and the triac?
Essentially an Scr is a solid state switch that will only allow current to flow in one direction. A triac is essentially two scr's in Anti- parallel that allows current to pass in both directions.

They are often found as the switching element in light dimmers and can be used as control elements in power supplies (variable or regulated).

Where does a SCR differ from a power transistor in operation?
thyristor can be scr or triac scr is strictly dc a triac is back to back scr's with a common gate two scr's back to back can be gated independently scrs cost less than triacs an scr can be combined with a full wave bridge to make an equivalent to a triac but this gives an additional 1.5V forward voltage drop
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.
