What else can I help you with?
When electrons flow in one direction what is that called?
The electrons flows from negative to positive and then positive to negative.The pole of the flow of electron changes at a time interval.This is called alternating current (AC).
Why is alternating current used in a conductivity cell?
Using DC the problem can be electrolytic action in the material being tested that causes the reading to change with time. AC prevents that happening.
What is electrolytic grinding?
maching by chemical action
Why ujt called current controlled negative resistance device?
The On/OFF action in UJT is controlled by emitter current
What is buffer action in digital electronics?
noninverting, increased current drive.
When electrons flow in one direction what is that called?

What happens when a battery is connected to a alternating current source?
this action is very dangerous and should not be considered.
What 9 letter word is electricity?
The word is galvanism. It means electricity produced by chemical action.
What peice of apparatus would you use to change chemical energy to electrical energy?
A battery uses a chemical action to produce direct current electrical energy.
What is the definition of ac electricity and dc electricity?
AC means alternating current and DC means direct current. The amplitude of AC voltage and current varies with time. Traditional AC electricity used in homes in the United States is a 60 Hertz sine wave. This means that 60 cycles of a sine wave occur every 1 second. Since AC voltage varies with time, the amplitude at each instant is different. The voltage changes from 0 to +Vpeak to 0 to -Vpeak and so on. Since the amplitude is always changing, the voltage quoted for AC such as 120 Vac for US homes is an average known as the Root Mean Square (RMS). The general formula for determining the amplitude of the voltage at any given time is: Vinst = Vpeak x sin(t) where Vinst is the instantaneous voltage at time t, Vpeak is the peak voltage, and t is the time. The relationship between Vrms and Vpeak for a sine wave is given by the formula Vrms = Vpeak / square root (2), so Vrms = Vpeak x 0.707 DC electricity does not vary with time. The voltage and current are constant at all times.
What does solar have to do with electricity?
Solar power involves converting sunlight into electricity using solar panels. When sunlight hits the panels, it generates a flow of electrons which creates an electric current. This current is then converted into usable electricity that can power homes and businesses.
What is meant by transformer action?
everything in the world is mechanically advantage.Answer'Transformer action' describes the process by which a voltage is induced into a secondary winding, due to a changing magnetic flux, created by an alternating current flowing through the primary winding, which links the two windings.
Why is alternating current used in a conductivity cell?
Using DC the problem can be electrolytic action in the material being tested that causes the reading to change with time. AC prevents that happening.
How does static electric differ from current electric?
Static electricity is a charge that is stored in a medium until it finds a way to discharge itself to a ground source .. scuffing your feet on a rug , socks help , will build a charge in you until you touch something ,, brother, door knob , lightening is a static charge, a capacitor uses a static charge Electric current is a constant flow of electricity from one place, a source thru a circuit and back to the source .. a battery is made to cause this flow thru chemical action .. the power in your house has various circuits that carry the electrical current flow thru the devices and appliances in your home
How can we define contact arcing?
Contact arching is the action of an electricity flow that uses surround air as a conduit to sustain its charge. This action take place after a spark breaks away from an electric current.
Why doesn't transformer work on a DC supply?
to have transformer action there should be an alternating magnetic flux.but dc supply cannot produce alternating flux.
What is chemical action?
A chemical action or reaction is a process that transforms one chemical substance to a new substance.
