What is the difference between DC and AC?
The primary difference between DC and AC is the direction of current flow. In a DC circuit, all electron current flow is in one direction. In an AC circuit, current flows in one direction for part of the time, and in another direction for another part of the time. In the AC circuit, we'll see current flowing "back and forth" instead of the unidirectional current flow we find in a DC circuit.DC is "Direct Current", and AC is "Alternating Current". In DC, the current flow is in one direction only. In AC, the current flow is constantly changing direction.An example of DC is the output of a battery. An example of AC is the power present in a home electrical system.The current whose magnitude and direction remains change called as alternating current.The current whose magnitude and direction remain unchanged called as d.c. Current.
What do you call something that cannot pass electricity?
Diode's are restrictive to one direction of current only. A resistor will limit the amount of current in a circuit.
What is the direction of conventional current in an external circuit?
The conventional direction of current flow in a DC circuit is from positive to negative. In reality the electron flow is from negative to positive. Most electronic schematics today still use the conventional current flow when drawn.
What is hystersis loss?
As the emf in an AC circuit causes current flow in the core of an inductor the magnetic dipoles will align themselves with the direction of the flow. As the current reverses the dipoles tend to stay aligned and there is a certain amount of flow that is required to realign them in the opposite direction. Thus there is a lag between current reversal and dipole realignment. The energy used for this realignment so to speak is called hysterisis and is a loss to the circuit.
What circuit is a circuit in which electrical current can follow only one path?
It is called a series circuit.
When current in a circuit reverses its direction in a regular pattern it is called?
An "Alternating Current" (AC).
Is the continuous flow of charge in a circuit called direct current?
No, the continuous flow of charge in a circuit is called electric current. Direct current (DC) refers to the flow of electric charge in a single direction, whereas alternating current (AC) changes direction periodically.
What is a electric current that's changes direction called?
An electric current that changes direction is called an alternating current (AC). In an AC circuit, the flow of electrons changes direction periodically, typically at a frequency of 50 or 60 Hz. This is in contrast to direct current (DC), where the flow of electrons is constant in one direction.
What is a device that reverses direction of electric current?
A device that reverses the direction of electric current is called a switch or a commutator. These devices can change the flow of current by opening or closing a circuit in the opposite direction. Such devices are commonly used in electrical systems to control the direction of current flow.
What is the direction of flow of current in a cell?
Current doesn't flow inside the cell. The cell is used to push current through an external circuit. The so-called "conventional" current flows out of the positive terminal of the cell, through the circuit, and back into the negative terminal of the cell. The confusing truth is that the actual physical carrier of current is the electron, which carries a negative charge. So the things that are actually moving and carrying the current through the circuit leave the dry cell from its negative terminal, physically flow through the circuit, and end up at the cell's positive terminal.

When reversed biased a diode acts like an open circuit?
The key function of a diode is to control the direction of the flow of current. Current passing through a diode can only go one way, which is called forward biased. In this setup, current is continuous hence the circuit is closed. When there is no current passing through, there will be no flow, and this is called reversed biased. In such a case, current is not continuous, hence it is called open circuit.

What is an electric current flowing in only one direction?
An electric current flowing in only one direction is called direct current (DC). This type of current has a constant flow of electrons in one direction from the negative to the positive terminal of a power source, such as a battery.
When electric current changes direction is called?
When electric current changes direction, it is called alternating current (AC).
What is a coil of wire with a current called?
current carrying coil
What is a electron flow in only one direction called?
A unidirectional flow of electrons is known as direct current (DC). In a DC circuit, the electrons flow in a constant direction from the negative terminal to the positive terminal of the voltage source.
