In vcd, input voltage controls the output current.e.g.jfet
In ccd , input current controls the output current. e.g. bjt
Current will flow as long as there is a difference of potential (a voltage) and a path for current to flow. So no power-control device is required for current flow but yes it will flow with a power control decive.
it is not a passive device .y because it is used to amplify the voltage and current .so as according to the definition of active device is the device which is used to amplify the current r voltage .hence transistor is a active device.
Yes
If resistance increases and voltage stays the same, then current decreases. Ohm's Law: Current equals Voltage divided by Resistance.
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.
Triac is the current control device.
transistor is a current controlled device. as the current flows through the base of the transistor , it works like a close switch.
The difference between a current control device and voltage controlled device is that for current controlled device, the current is constant and the voltage is variable while for a voltage controlled device, the voltage is constant and the current is variable.
Potential meter is voltage control device and rheostate is current control device. it is a basic difference.
Current will flow as long as there is a difference of potential (a voltage) and a path for current to flow. So no power-control device is required for current flow but yes it will flow with a power control decive.
it is not a passive device .y because it is used to amplify the voltage and current .so as according to the definition of active device is the device which is used to amplify the current r voltage .hence transistor is a active device.
Yes
BJT is a example for current controll device. And JFET is a voltage controlled device.
A device for measuring voltage, amperage and current.
If resistance increases and voltage stays the same, then current decreases. Ohm's Law: Current equals Voltage divided by Resistance.
RPS is only the voltage& power controlled device. it can only used for set the input for our wish A device which can change its output according to the voltage supplied to it is called a voltage controlled device.ex. a voltage controlled current source,or a field effect transistor. In a voltage controlled current source the output current changes as the voltage supplied to it changes.
