The expression alternating current refers to which form of energy?
Wiki User
∙ 13y ago
Alternating current is a flow of electrical energy in which the direction of electron flow reverses periodically. The mains electricity in your house is likely Alternating Current. The other form is Direct Current, where the direction of electron flow is in one direction only. Such as the flow from the batteries in your flashlight.

In electronics the term rectification refers to the process of changing an alternating current AC to what?
A Direct Current
What is meant by negative half-cycle of an alternating current?
Alternating current varies in magnitude, and reverses direction every half-cycle. When the current is drifting in one direction we allocate it a 'positive' direction; when it reverses direction we allocate it a 'negative' direction. So the positive half-cycle refers to its variation in current during its forward or positive direction and the negative half-cycle refers to its variation in current during its reverse or negative direction.
An electric current is the measure of what?
An electric current is a movement of charges, and it is measured in amperes or just amps. An ammeter is used to make this measurement. Current flow is a scalar quantity, and it refers to the number of charges passing a given point per unit of time.
Why was the ac electrical generator invented?
"AC" is just a scientific term that refers to the fact that this generator produces electricity in an Alternating Current as opposed to "DC" which refers to Direct Current. Commonly, the plug outlet on the wall is AC, and the little black box electrical adapter for your cordless telephone is changing that AC current into DC current for the phone to work on. The phone line in your house runs on 24 volts DC, where the wall sockets are 124 volts AC.
What is the DC volts?
DC voltage refers to "direct current," and it can mostly be found in batteries. It means that it flows constantly through the circuit, as opposed to AC (alternating current) which switches flow quickly. There are benefits and downsides to direct current, the benefits being that it is best suited for low-current applications and is easy to work with, the downside being that it loses energy quickly as it flows and cannot reach very high power (voltage).AnswerIn this context, 'd.c.' is being used as an adjective to describe the nature of the voltage.
Define alternating current definition?
The alternating current refers to the flow of the electric charge periodically and in the opposite direction. The polarity changes with the time..
In electronics the term rectification refers to the process of changing an alternating current AC to what?
A Direct Current
What is DC-AC?
AC/DC is a rock band. Their name refers to "alternating current direct current.
Is an alternating current the same as air condition?
No. Not the same. AC means Alternating Current which refers to a type of electrical flow (electrons). The word "Alternating" eaning that the current of electrons changes direction based on its frequency -- e.g., 60 times per second. A/C means Air Conditioning and refers to a machine that cools the air.
What is the mean by the word A'C in electical system?
AC refers to Alternating Current, as opposed to DC which is Direct Current.
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.
What is meant by negative half-cycle of an alternating current?
Alternating current varies in magnitude, and reverses direction every half-cycle. When the current is drifting in one direction we allocate it a 'positive' direction; when it reverses direction we allocate it a 'negative' direction. So the positive half-cycle refers to its variation in current during its forward or positive direction and the negative half-cycle refers to its variation in current during its reverse or negative direction.
What are the differences between AC power and DC power?
The description AC/DC refers to equipment designed to be operate on either alternating current (AC) or direct current (DC). In alternating current the movement of electric charge periodically reverses direction. In direct current , the flow of electric charge is only in one direction.
Where is solar energy obtained from?
Solar refers to the sun as in our solar system. Solar energy is energy obtained from the sun. It may be just energy that is collected as heat such as what collects in a closed room from passing through windows or it may be energy that is collected by solar cells and converted by them to electricity. This electricity is usually then stored in wet cell batteries for later use as direct current or further conversion to alternating current to be used with household or other appliances.
What is electrical energy transmission?
I would guess it refers to transmitting energy using an electrical current.
What is current direction?
Outside the battery, it is negative to positive and inside the battery it is positive to negative.
An electric current is the measure of what?
An electric current is a movement of charges, and it is measured in amperes or just amps. An ammeter is used to make this measurement. Current flow is a scalar quantity, and it refers to the number of charges passing a given point per unit of time.
