Current that reverses direction in the regular pattern is called?

This is known as a direct current or DC. The two major types of currents are AC (alternating current) and DC (direct current). In AC the charges move back and forth, but in DC the charges flow in JUST ONE DIRECTION. Due to this characteristic it will not reverse direction like AC can.


What is different between alternating current and direct current?

Direct current is constant - always in the same direction. Alternating current regularly changes direction; for example, in household current, 50 or 60 times (that is, full cycles) in every second.See the Related Link below for more information about the difference between alternating current and direct current.


An electric current is the measure of what?

An electric current is a movement of charges, and it is measured in amperes or just amps. An ammeter is used to make this measurement. Current flow is a scalar quantity, and it refers to the number of charges passing a given point per unit of time.


Which type of current invovles flow of charge in two directions?

A direct current involves change of flow in a single direction. DC (direct current), at least on the macro scale. On the atomic scale, they seem to wander all over the place between atoms, and the average movement is what we measure as current.


What is an Esaki diode?

A diode is a semiconductor electrical component that allows an electric current in only one direction. A tunnel diode, or Esaki diode, is a special type of diode that can operate very quickly using quantum tunneling, allowing it to work even with microwave frequencies (current switching direction billions of times per second).
