What is the definition of limit test for inorganic compound?
limit test is a quantitative or semiquantitative test designed to identify and control small quantities of impurity which are likely to be present in the substance.Basically limit test for inorganic compound is carried out so that the amount of inorganic impurity present in the drug or required material do not exceed its prescribed limit.
How can you build a remote control electronic device that will press a button?
You build an electronic device to control a transistor switch that causes a mechanical device to push the switch. Now days we bypass the mechanical switch and the circuit can do the switching.
What does mio ton of fossil CO2 mean?
ABATEMENT: The reduction of pollutant discharge by means of process modification, shutdown or addition of control equipment.
Is it appropriate to connect cancer and the cell cycle?
Yes. Cancer is caused by an unregulated cell cycle, causing the cells to multiply rapidly out of control. In addition, they proliferate primarily with fructose.
What is function of Control Systems?
A control system can be as small as you can barely see or as large as the USA. The national power grid - or all the utilities supplying power to each one of the states - is one such example. Control engineering is responsible for ascertaining that this system is in operation at all times 24/7/365. In addition there are human operators who monitor the system's status constantly and, if there is a fault, system engineering is involved to solve the fault and take corrective actions.
How do you use the Transistor output terminals of an electronic counter in a Electrical control circuit?
They use transistor as the purpose to transfer the voltage
What is a power transistor on a Hyundai scoupe?
its the ignition control module
Is BJT is a current control device or voltage control device?
transistor is a current controlled device. as the current flows through the base of the transistor , it works like a close switch.
What is direct couple transistor logic?
Direct coupled transistor logic is a type of transistor that is more economical to use then integrated circuits. These transistors can be found in many types of wires such as the ones that control cable internet.
What is FET?
FET is abbreviation of Field Effect Transistor. This is a transistor in which current is controlled by voltage only and no current is drawn. It is a high input impedence device and is used in computers, telecommunication and control circuits. This transistor is better in certain parameters as compared to BJT, that is Bipolar Junction Transistor.
What is saturation and active region in a transistor?
The output current of a transistor is controlled by the current in the 'base' input: Increasing the control current will increase the output current in a more or less linear fashion. In the saturation region, this is no longer true: The transistor is nearing the limits of how much current it can conduct, so increasing the control current further has little or no effect. When using a transistor as an amplifier, you want to stay away from the saturation region as it would distort the signal you are amplifying. When using a transistor as an on/off switch, as in digital circuits, being in the saturated region is 'on' and a normal mode of operation.
How does a npn transistor switch work to switch a load on and off?
let's insert a transistor in place of the switch to show how it can control the flow of electrons through the lamp. Remember that the controlled current through a transistor must go between collector and emitter. Since it is the current through the lamp that we want to control, we must position the collector and emitter of our transistor where the two contacts of the switch were. We must also make sure that the lamp's current will move against the direction of the emitter arrow symbol to ensure that the transistor's junction bias will be correct as in Figure below(b).
What are thermal transistors?
Thermal transistor is an efficient heat control device which can act as a heat switch as well as a heat modulator.
What is wrong when basic electric RC car moves back but not forward?
well either the radio control is not sending the signal or you burnt a transistor in the circuit board. that means you have to find the faulty transistor and switch it for another identical one.
What is the purpose of the base of a transistor?
Recombination of negative and positive charge carriers
Why is the base current in transistor very small?
Because a transistor's collector current is proportionally limited by its base current, it can be used as a sort of current-controlled switch. A relatively small flow of electrons sent through the base of the transistor has the ability to exert control over a much larger flow of electrons through the collector.
What is a blower transistor?
There isn't a transistor but there is a blower motor resistor. The purpose of it is to control fan speeds. Normally when it goes bad it will let the fan run on high only. It is located under the dash on the passenger's side near the blower motor.
