What are electrodes called in a MOSFET transistor?
The terminals on a MOSFET are called the "Source", "Drain", and "Gate". Just as with a bipolar junction transistor (BJT) the direction of current flow will be based on the doping configuration of the semiconductor. In a MOSFET, the doping configuration can be either n-channel or p-channel, but with MOSFETS, they also come in a "normally on" or "normally off" configuration, which is specified by being either "depletion mode" or "enhancement mode", respectively.
What is variable alternating current?
A current which changes its direction of flow again and again is known as alternating current.
Can a diode work in ac?
A diode is a "one-way valve" that allows electrical current to flow in only one direction. A diode placed in series between an AC voltage source and a resistive load will allow current to flow through the load in one direction and block the current when the polarity of the AC voltage changes.
Difference between electron flow and conventional current?
Conventional current flow refers to a flow of positive charges. It is a kind of ficticious current. If - as is often the case - the real current is an electron flow (negative charges), then the conventional flow is a current in the opposite direction as the electron movements, since this would have the same effect (for example on the magnetic field, or on conservation of charge).
What enables the electric current to move through a material?
The electric current moves in the direction opposite to the flow of electrons by convention.When a potential difference is applied to a material which has "loose" electrons, the electrons move in a direction opposite to the potential gradient and the current moves in the opposite direction to the flow of electrons.This is how current flows in materials.
Why mosfet is not removed from the circuit when the supply is on?
it can exchange the current is much larger and has Avery low resistance when it is turned on.the mosfet is not removed from the circuit when the supply is on because it flow the high current.
When the flow of a current is aways in one direction?
When the flow of current is aways in one direction it is known as direct current.
What is the direction of current due to flow of electrons if it is not conventional current?
The direction of current due to flow of electrons is opposite to the direction of conventional current. This is because electrons have a negative charge, so when they flow in a wire, they are actually moving in the opposite direction to the current flow defined by convention.
What is the electrical current in a circuit?
Conventionally electric current was assumed to be a flow of positive charges. But in reality especially in metals electric current is due to the flow of negatively charged electrons. So direction of conventional current is opposite to the direction of flow of electrons. But in case of liquids as well as solids electric current is due the flow of both positive and negative ions.
What additional factor will be change if the direction of a current flow is change?
direction of magnetic field
When using kirchhoffs current law if negative answer is found for current flow what does this indicate?
A negative answer in a Kirchhoff's Current Law calculation indicates that the assumed direction of current flow was incorrect. It suggests that the actual direction of current flow is opposite to the assumed direction. Therefore, the sign of the calculated current should be corrected to reflect the actual flow direction.
What are electrodes called in a MOSFET transistor?
The terminals on a MOSFET are called the "Source", "Drain", and "Gate".

What do the two types of electricity have in common?
Both alternating current (AC) and direct current (DC) are ways to transmit electricity. They both involve the flow of electrons through a conductor but differ in the direction of the flow and how they are produced.
What is a current consisting of charges that flow only in one direction called?
A current consisting of charges that flow only in one direction is called direct current (DC). In DC, electrons flow continuously in one direction from the negative to the positive terminal of a power source.
What current that does not reverse its direction of flow?
Direct current (DC) does not reverse its direction of flow. This means that the flow of electrical charge in a DC circuit always moves in one direction, from the positive terminal to the negative terminal.
Can current flow both ways through a lamp?
Yes, we use AC (alternating current) in our homes, the current changes direction 120 times a second.
Why is current a vector?
Current Density describe how charge flow at certain point since current density = I/A and the vector direction tells you about the direction of flow at that point.
