Electrical current is the number of elementary charge units (coulombs) that pass by a given point in one second. Current, measured in amperes, is coulombs per second.
Electrical voltage is the "pressure" behind that current. Voltage, measured in volts, is joules per coulomb.

Potential difference between -1 and 2 volts?
3 volts
How many watts are in 30 volts?
There is no direct relationship between watts and volts. Watts = volts x current in amps.
What is the resistance of a conductor that carries a current of 120 amperes when the potential difference between its ends is 240 volts?
V/I = R --> R = 2 ohms.
What do you call the measure of electrical pressure?
Electrical pressure is the difference in electrical potential between two points with or without current flow. Without current flow it known as an EMF (electro motive force E) with current flow it is described as a potential difference (pd V). Both are measured in volts (symbol V).
What Difference between D cell and AA cell?
Size is the difference - both supply 1.5 volts
What is the potential difference between 10.2 volts and -12.4 volts?
22.6 volts
Potential difference between -1 and 2 volts?
3 volts
What is the potential difference measured in volts?
'Force' isn't measured in volts. Potential and potential difference are measured in volts.
The force measured in volts?
Voltage is what is measured in volts. This is the electric potential difference between two places. The electric current is also measured so as to ascertain the voltage.
Is potential difference measured in volts or amperes?
Volts; The Ampere is the unit for current in charge per second.
What is the difference between 24VAC and DC 24V1.0A output?
I can say that 24VAC means 24 volts alternating current. 24VDC @ 1A means 24 volts direct current delivered at 1 ampere. So the difference I suppose would be: 1. Alternating current VS. Direct current 2. X Amperes(VAC) VS. 1 Ampere (VDC)
What is the difference between power and current?
It's the difference between pressure and flow. The pressure is measured in volts, and the current in amps.Current is the flow of electrons.Power=VIcosϕV=voltageI=currentCosϕ=cosine of angle between V and IAnswerCurrent is a drift of electric charge, expressed in amperes. Power is the rate of doing work, expressed in watts (equivalent to a joule per second).
What difference between a kilovolt and volt?
999 Volts A Kilovolt is 1000 volts.
How do you convert 100 volts into Ampere's?
it is impossible to convert volts into amperes, because there are two different units of measurement. Volts refers, as you know, to voltage, or the electric potential difference between two points, and amperes refers to the current, or the intensity of the electric current. Its like trying to convert horses into donkeys.
How many watts are in 30 volts?
There is no direct relationship between watts and volts. Watts = volts x current in amps.
What is the difference between heavy and light current in electrical engineering?
light current deals with control and telecommunication.while heavy current deal with machine which consume high current such as transformer ,generator ,electrical distribution above 415 volts
What is the difference between mains electricity and batteries?
The first difference is that mains power is AC (Alternating Current) whereas batteries are DC (Direct Current). The second difference is the amount of available amperage; mains have the capacity to deliver higher current for an indefinite amount of time, where batteries will drain faster the more current is pulled. Your normal A/AA/C/D/9V batteries only produce 500 milliamps (1/2 an amp) at their nominal voltage (1.5 or 9v). Mains current (for the U.S.) is 110 or 220 volts in residential. Commercial mains, such as in factories, can be 110, 208, 220, or 440 volts. A big difference between residential and commercial electricity is the available phasing. But that's another discussion.
