The SCR and TRIAC are essentially controlled diodes.
A diode mainly consists of only 2 terminals(anode,cathode).A SCR mainly contains one more terminal called GATE.The main purpose of the gate in an SCR is just to provide pulses.The main draw back of SCR is it is not fully controllable device.
payroll is not controllable cost.
I have several sentences for you.That horse is not controllable.The scientific variable is controllable in the laboratory.I want a controllable temper!
No, a Transistor operates with a modulated direct current. You need 4 Diodes to manufacture a rectifier to deliver direct current at the outlet, with alternating current at the input. A Diode is effectively a one way valve to address one halve of the cycle of the alternating current.
Electricity cost not a controllable cost. The manager cannot influence this type of expense. To the extent where a cost cannot be managed it is indeed a non controllable, now for electricity, to the extent where consumption can be raised or lowered it becomes a controllable cost. If the consumption can be optimized through processes or equipments it then is a controllable cost.
You are talking about a special type of diode called a zener diode which is designed, using special junction doping, to allow controllable reverse bias operation at a reduced breakdown voltage with a much sharper knee point curve than its normal forward breakdown curve. This allows the diode to be used as a voltage regulator. Normally, a diode's reverse breakdown curve is such that, at reverse breakdown, it avalanches and, without current limits in place, will self destruct. The zener diode, on the other hand, will operate in reverse much the same as it does in forward, just at a different voltage, and with a much sharper current to voltage curve, making it highly suitable as a voltage regulator.
zener diode :zener diode operates under reverse bias voltageideal diode :ideal diode operates under forward bias voltage
yes, diode can be used as rectifier diode to convert ac to dc
The read type diode are called impatt diode
A diode is used primarily as a Rectifier
Laser diode
zener resistance of a zener diode is the resistance of the zener diode but which is the resistance of a diode
