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.
Can current flow in an incomplete circuit?
Maybe there's no voltage-source(AC or DC) because voltage is the one that motivates electrons to flow. It could be the connection of components in your circuit.
What Happens When an AC of 5A and dc current of 5A flow simultaneously through a circuit?
it will be the polarized sum of the two quantity
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.
Why diode is used?
The purpose of a diode is to direct the flow of current in a circuit. Diodes function by allowing current flow in only one direction (acting as a short when current is applied at one end) and resisting current flow from the opposite direction (acting as an open circuit). Electronic devices such as full wave rectifiers use a series of diodes to convert AC to DC current.
The opposition to the flow of electrical current?
In a DC circuit . . . resistance. In an AC circuit . . . impedance.
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.
What does AC and DC stand for in electrical field?
Alternating Current and Direct Current. Electricity is voltage and current. Voltage is electrical pressure, and current is the flow of charged particles. The difference between alternating current (AC) and direct current (DC) is that the electrons in an AC circuit regularly reverse their direction. In a DC circuit electrons always flow in the same direction.
What does AC and DC stand for in the electrical field?
Alternating Current and Direct Current. Electricity is voltage and current. Voltage is electrical pressure, and current is the flow of charged particles. The difference between alternating current (AC) and direct current (DC) is that the electrons in an AC circuit regularly reverse their direction. In a DC circuit electrons always flow in the same direction.
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 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.

Do electrons flow in only one direction?
Yes. Electrical current only flows in a closed circuit. If it were an open circuit, there would be no current.AnswerAn interesting question. The answer is.... not necessarily! I say this because a capacitor is an open circuit, yet it allows d.c. current to flow for a short period of time (while it charges), and it allows a.c. current to flow continuously.
Can current flow in an incomplete circuit?
Maybe there's no voltage-source(AC or DC) because voltage is the one that motivates electrons to flow. It could be the connection of components in your circuit.
What blocks current flow?
Resistors "resist" current flow. The ultimate "blocking" resistor is an open circuit, having a resistance of infinity (for all practical purposes) ohms.Capacitors also resist a change in voltage drop. For the case of a DC circuit, a capacitor, after reaching equilibrium, will present a DC resistance of infinity. For the case of the AC circuit, a capacitor will allow the AC signal to pass, while blocking any DC bias that might be present.So, resistors and, in the DC case, capacitors, block current flow.
What is your observation of the current in series circuit?
The current in a series circuit will be directly proportional to the voltage applied to the circuit, and inversely proportional to the resistance in it. Additionally, there will be one and only one path for that current, as it is a series circuit. All the current in the circuit will have to pass through each each element of the circuit. The current will all flow in one direction in a DC circuit; current is unidirectional. And will flow "back and forth" in an AC circuit, or will alternate directions, as one might expect.
