Difference in potential between two points. Like the voltage of an energizer AA battery is 1.5 volts BETWEEN its terminals. If you place two AA batteries in a flashlight, the voltage of the series combination of AA batteries from one tip to the other is now 3 volts.

How many volts is low voltage?

Low voltage by definition means any voltage from 31 to 750 volts inclusive.


How many volts is low voltage electricity?

Low voltage electricity typically refers to voltages below 1000 volts. It is commonly used in residential, commercial, and industrial applications to power lighting, appliances, and other electrical devices.


Is 30 volts of AC voltage the same as 30 volts of DC voltage?

30VAC is not equal and will never be equal to 30VDC. If you rectify 30v ac to DC you will get a voltage lower than 30v because there would be a voltage drop across the rectifier=diode,capacitor,resistor and transistors or thyristor, depending on the make of the rectifier.AnswerAs the questioner makes no mention using a rectifier, yes, 30 V a.c. is exactly equivalent to 30 V d.c. This is because a.c. voltages are root-mean-square values (unless otherwise stated) which, by definition, correspond to d.c. voltages.


What is the relation of current voltage resistance to one another?

Under normal circumstances, the relationship is given by Ohm's lawvoltage = current x resistance.The ratio of voltage to current is called resistance. This is obtained from the definition of the ohm, and not (as so often stated) from Ohm's Law.If the ratio of voltage to current is constant for variations in voltage, then the load obeys Ohm's Law and is called a 'linear' or 'ohmic' load.If the ratio of voltage to current changes for variations in voltage, then the load does NOT obey Ohm's Law, and is called 'non-linear' or 'non-ohmic'. Pure metal conductors ONLY obey Ohm's Law if their temperature is held constant. No semiconductor obeys Ohm's Law.


When there is more electrons does it mean the voltage will be higher or the current will be higher?

Having more electrons typically means that the current will be higher, as current is the flow of electrons. Voltage, on the other hand, is a measure of the electric potential difference between two points and is not directly related to the number of electrons present.
