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).
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.

What is the relationship between the direction of current and direction of electron flow in a current-carrying wire?
because the current is actually the flow of electrons.
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 a circuit called if its operating and the current is flowing?
This is called a closed circuit. If current was not flowing, it would be open.
What is a coil of wire with a current called?
current carrying coil
What is alternated current?
That refers to a current in which the direction of flow changes continuously. In household current, this usually happens at 50 or 60 cycles per second (depending on the country), but the definition of alternating current can include just about any other frequency, as well.
The opposition to the flow of electrical current?
In a DC circuit . . . resistance. In an AC circuit . . . impedance.
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 a break in an electrical circuit called?
A break in an electric circuit is called an open circuit. Electric current will not flow through an open circuit.
