Why does heater come on for awhile then after it turns off it turns right back on?
because you touch yourself at night
What is the action off iodine on starch?
It turns it orange.
What turns off transcription by binding to the operator?
A repressor protein turns off transcription by binding to the operator region. By binding to the operator, the repressor prevents the RNA polymerase from binding to the promoter region and initiating transcription. This prevents the expression of the gene or genes downstream of the operator.
What is an example of a time switch?
A time switch is either an electrical or manual device that allows you to set when you want something to come on and when you want it to turn off. A typical example is the time switch that turns on your central heating an hour before you arrive home from work. And it turns off an hour when you have usually gone to bed at night.

What is the actual use of moc3011?
When people build systems that automatically turn on and off light bulbs and other mains-powered devices, they typically use a microcontroller to decide when to turn things on and off. Alas, microcontrollers cannot be directly connected to mains power. So these people typically build a system to allow the microcontroller to indirectly turn on and off the light bulbs: First, the microcontroller turns on (or off) a small LED inside an optoisolator, when turns on (or off) the silicon switch inside the optoisolator, which turns on (or off) a triac. The triac acts just like a light switch, turning on (or off) the light bulbs or other mains-powered devices attached to it. The MOC3011 triac driver optoisolator is often used in such applications.
What signal allows AC to flow through terminal T1 to T2 on the Triac?
A: It depends on the current load but the Small terminal is the gate that will allow the triac to conduct. However the gate cannot be used to shut it off, The only way to shut it off is t reduce the current below the holding current or revering the polarity for the triac when conducting
What is the population of Triac-Lautrait?
Triac-Lautrait's population is 454.
Difference between diac and triac?
The diac and the triac are used to control the AC lines. The difference is that triac are bigger than diac.
How can a triac be used to control the power of an AC motor?
A TRIAC is a solid state device that turns on at a specified phase angle in the AC wave form and then turns off at the next zero-crossing. It also works backward, in that you can turn it on on the negative going phase with a negative going pulse on the gate. By varying the phase angle of the turn-on point, you can provide varying voltages, ranging from full line voltage to a small fraction of the line voltage. By varying the voltage to a motor, you can thus vary the power, optimizing it for power factor and/or speed. Often there is another TRIAC, one with two terminals, called a DIAC, in series with the gate of the TRIAC. This allows you to balance the firing points, with the effect of balancing the phase voltages for both the plus and the minus side. This reduces DC bias on the line.
What is the area of Triac-Lautrait?
The area of Triac-Lautrait is 6,400,000.0 square meters.
How does triac works?
Triac is Three Layered Device . Emitter ,Collector and Gate
What is the full form of TRIAC?
TRIAC is the word derrived from the 2 words TRIode and AC.
State two advantages of a triac as compared to an SCR?
triac act as a ac contactor
Circuit diagram of illumination controller using diac and triac?
a circuit diagram consist of diac&triac

What are the applications of a triac?
A triac is a semiconductor-based solid state electronic switch. The main applications are those which require the electronic switching of AC circuits. The switching can go from 100% on to 100% off (or vice versa) or can allow only portions of each AC cycle to pass through, which varies the amount of power supplied to the load. That is how triac-based AC lamp dimmers work.
