AC (Alternating Current) - It fluctuates from +ve to -ve (Ie- positive voltage to
negative voltage), it does this constantly, hence why it alternates.
DC (Direct Current) - It has a constant supply of electricity but the voltage does not change at all. It goes in one direction ONLY.
Main difference: AC changes the voltages from positive to negative CONSTANTLY (current goes up & down), and DC has a continuous supply of current which flows IN ONE WAY.

What is the basic difference between carbon brush of AC slip ring motor and carbon brush of Direct current commutator motor?
The main difference is in how the carbon brushes are used. In an AC slip ring motor, the brushes transfer power to the rotor through slip rings, whereas in a DC commutator motor, the brushes switch the current direction on the rotating armature to maintain torque and rotation. Additionally, the design and composition of the brushes may vary to accommodate the specific requirements of each motor type.
Why neutral wire does not carry current in closed ac circuit?
The neutral wire does carry current in a closed AC circuit. Clamp a clamp on amp meter around the neutral wire directly after the circuit load and it will read the same current as is on the "hot" wire.
Is converting ac to watts and dc to watts the same watts equals volts times amps?
Yes, watts is still volts times amps, for both ac and dc circuits. The complexity lies in the phase angle between voltage and current. If the circuit is purely resistive, the phase angle will be zero. If the circuit is capacitive or inductive, the the phase angle will vary, depending on frequency and on how much capacitive or inductive reactance there is. The difference comes into play when you consider true versus apparent power.
What is 300 VAC?
300 VAC stands for 300 volts AC, which is the measure of electrical potential difference in an alternating current (AC) circuit. It signifies the peak voltage that the circuit can reach.
What makes a dc bulb different from an ac bulb?
The voltage source that is applied to them is the difference between AC and DC light bulbs.
What is the difference between ac and dc grounding?
The difference AC and DC grounding is that AC is alternate current and DC is direct current. Grounding for both AC and DC is the same.
What is the phase difference between the current through the resistor and inductor in an AC circuit?
The phase difference between the current through the resistor and inductor in an AC circuit is 90 degrees.
What is the difference between AC and AD?
AC is alternating current and AD is Anno Domini or after Christ.
What is the difference between current (DC) and alternating current (AC)?
ac comes directly from the power socket, and DC is battery source. Answer2: The frequency is the difference, AC has frequency f>0 and DC does not f=0.
What is main difference between ac power and dc power?
AC power is made by alternating current and DC does not change.
Can you give any practical prove of difference between the ac and dc?
if ac changes direction then how current happen to flow
What is the difference between elecrical and electronics?
in electronics we use DC current but in elctrical equipment we use AC current
Why phase difference exists between voltage and current in ac circuit?
because of the reactances in the circuit
What type of current comes from wall socket?
Typically alternating current (AC) comes from wall sockets. This article explains why: http://www.wisegeek.com/what-is-the-difference-between-ac-and-dc.htm
What is the difference when selecting a cable between AC and DC current?
AC. is alternating current and Dc is direct current. alternating equivalant to pulsating electricity while direct is a constant draw with little fluxuation.
What is the difference between ac voltage and dc voltage?
access current ( like plugs in your house ) direct current (like batteries)
What is the basic difference between ac and dc?
AC electricity (Alternating Current) flows in both directions along the wire at a certain frequnecy eg 50 or 60HZ (eg the wall outlet is AC) DC electricity (Direct Current) flows along the wire in one direction only, from positive to negative (eg you car battery is DC)
