What else can I help you with?
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.
Why BJT is called bipolar device and FET an unipolar device?
FETs can be called UNIPOLAR devices because the charge carriers that carry the current through the device are all of the same type i.e. either holes or electrons, but not both. This distinguishes FETs from the bipolar devices in which both holes and electrons are responsible for current flow in any one device.
A device that increases the voltage of an alternating current is called?
That's called a transformer.
What is Primary Current?
Primary current is a flow to be measured that cannot be safely passed through the measuring device. A current transformer is used to provide a lower level, secondary current that can be passed safely through the measuring device. Primary current is measured as a secondary current, multiplied by the turns ratio in the current transformer.
Why bjt is called current controlled current device?
Because the operation of the transistor is determined by the current at the base. the principle equations of BJT operation are: Ic = h*Ib ,and Ie=Ib+Ic thus device operation is controlled by the input current.
What is a device that contains a thin strip of metal that will melt if there is too much current through it is called?
A fuse
How current are made?
You cause the current to flow through an electronic device that allows current to flow in one directionbut not in the other direction. Such a device is called a "diode" or a "rectifier".
On what factors the current flowing through a device depends?
Current flowing through a device depends on resistance offered by that device.
A device that contains a thin strip of metal that will melt if there is too much current through it?
A fuse has a metal strip that melts and opens a circuit if the current becomes too great.
The device that turns a needle in a galvanometer is called an electromagnet?
The device that turns a needle in a galvanometer is called a coil or a solenoid. It generates a magnetic field when current passes through it, causing the needle to deflect in response to the current being measured.
What is offload device?
an off-load device a a switch where there is no current passing through it when its switched, a isolator is a off load device, a light switch is a on-load device because there is current passing through it when its switched.
Is a light bulb an electromagnet?
No, a light bulb is not an electromagnet. A light bulb contains a filament that produces light when current flows through it, whereas an electromagnet is a device that produces a magnetic field when current flows through a coil of wire.
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.
Increasing the current flowing through this device makes it stronger?
no it does not make stronger.... if the device does not have that capability to with stand tat current...... the device will be destroyed........
What is unwanted heat loss called in electricity?
Unwanted heat loss in electricity is called resistive loss or I2R loss, where I represents the current flowing through a device and R represents the resistance of the device. This type of energy loss occurs as heat when electrical current passes through a conductor with resistance.
What is the name for the device that changes the direction of the current?
A device that changes the direction of the current is called a "switch" or a "reversing switch." This device allows for the current to flow in different directions as needed.
Why BJT is called bipolar device and FET an unipolar device?
FETs can be called UNIPOLAR devices because the charge carriers that carry the current through the device are all of the same type i.e. either holes or electrons, but not both. This distinguishes FETs from the bipolar devices in which both holes and electrons are responsible for current flow in any one device.
