n alternating current (AC, also ac) the movement of electric charge periodically reverses direction. In direct current (DC), the flow of electric charge is only in one direction.
AC is the form in which electric power is delivered to businesses and residences. The usual waveform of an AC power circuit is a sine wave. In certain applications, different waveforms are used, such as triangular or square waves. Audio and radio signals carried on electrical wires are also examples of alternating current. In these applications, an important goal is often the recovery of information encoded (or modulated) onto the AC signal.
What else can I help you with?
Which current is used in houses?
Alternating current (AC) in almost all cases.
The kind of electricity from the power plant is called?
There are only two kinds of electricity, direct current and alternating current. All power plants now produce alternating current
How far does the current go before it reverses in a alternating current?
all the way to the load
What is the purpose of a alternator?
A car alternator generates alternating current, then uses a rectifier to convert the alternating current to direct current, it charges your battery and supplies the current to run all the electrical systems in the car.
How did Nickola use electricity?
Nikola Tesla was the inventor of the alternating current light and power system in use all over the world today.
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.
Does current flow in all AC motors alternate direction?
Yes, in alternating current (AC) motors, the current flows in alternating directions. This is due to the nature of AC power, where the voltage periodically reverses direction, causing the current to do the same. This alternating current creates a rotating magnetic field that drives the motor's rotor. In contrast, direct current (DC) motors have current that flows in a single direction.
What is ac and what is DC?
DC stands for "direct current", AC for "alternating current". A direct current flows in a single direction; an alternating current changes its direction all the time, typicall 100 or 120 times a second (twice the frequency, which is measured in hertz).
What is household electricity called?
household electricity is called alternating current because when you have elecricity in your home,your elecricity will travel all over your house to make the electricity flow.
What is direct current and alternating current?
Direct current is a constant, steady state current, such as obtained from a battery. Alternating current is constantly switching polarity, usually in a sinusoidal waveform, such as obtained from an alternator, a form of generator that does not have a commutator.Direct Current and Alternating Current:The first and simpler type of electricity is called direct current, abbreviated "DC". This is the type of electricity that is produced by batteries, static, and lightning. A voltage is created, and possibly stored, until a circuit is completed. When it is, the current flows directly, in one direction. In the circuit, the current flows at a specific, constant voltage (this is oversimplified somewhat but good enough for our needs.)The other type of electricity is called alternating current, or "AC". This is the electricity that you get from your house's wall and that you use to power most of your electrical appliances. Alternating current is harder to explain than direct current. The electricity is not provided as a single, constant voltage, but rather as a sinusoidal (sine) wave that over time starts at zero, increases to a maximum value, then decreases to a minimum value, and repeats.
What does the term frequency mean in electricity?
That refers to AC (alternating current). A direct current flows only in one direction; an alternating current changes its direction all the time. The "frequency" refers to how often the current changes direction. It is expressed in hertz (Hz), which means the same as cycles/second.
Does lithium cadmium provide a direct or an alternating current?
All batteries provide DC. It does not matter their makeup.
