Voltage (of a circuit) as defined in the NEC: n. The greatest root-mean-square(rms) (effective) difference of potential between any two conductors of the circuit concerned. Voltage as defined by Webster's: n. Electromotive force or potential difference, usually expressed in volts.

Define the puncture voltage?
whta is puncture voltage
What is the instrument called that can change electrical voltage?
Electrical voltage can be changed by a transformer.
Is there a theoretical limit to high voltage?
Theoretically there is no limit to the voltage of an electrical current.
Why does voltage matter?
Voltage is a measure of electrical potential. I understood voltage best when my first semester Electronics professor told the class that voltage is to an electrical circuit as water pressure is to a plumbing "circuit".
What is the unit of electrical voltage?
The Volt
What is considerede low voltage?
Low voltage is a relative term, as there is no 'level' at which a voltage is rated 'low'. Electrical safety codes define low voltage as circuits that do not require the same protections necessary at higher voltages.
Define voltage in terms of electric potential energy and charge?
When unlike charges are moved farther apart, they gain electrical potential energy. Electrical potential difference is the change in potential energy per coulomb of charge. Voltage is the common name for electrical potential difference and is measured in volts (V). Electrical energy depends on the amount of charge and voltage. Electrochemical cells, or batteries, are a common source of voltage. We use voltmeters to measure potential difference. :)
Define the puncture voltage?

Does a transformer provide electrical energy that is produced chemically?
No. A transformer transforms electrical energy, from one voltage to another voltage.No. A transformer transforms electrical energy, from one voltage to another voltage.No. A transformer transforms electrical energy, from one voltage to another voltage.No. A transformer transforms electrical energy, from one voltage to another voltage.
What is the instrument called that can change electrical voltage?
Electrical voltage can be changed by a transformer.
In an IEC-320 plug which wire carries electrical voltage?
the hot wire carries the electrical voltage
Define electrical conductivity?
Conductivity is the inverse of resistance. Since Ohm's Law states that current is voltage divided by resistance, it also states that current is voltages times conductivity.
Define Mechanical Electrical and Plumbing Engineer?
Mechanical and Electrical
Define the electrical term VA?
'VA', or more correctly, V.A, is not an electrical 'term'. Rather, it is the symbol for 'volt ampere', the unit of measurement for a quantity called 'apparent power'. This is the product of the supply-voltage and load current for an a.c. load.
How is different between voltage and current?
voltage = the electrical "pressure"current = the electrical "movement rate" or "flow rate"
What is a short to voltage?
what is short to voltage in a car electrical circuit & how to check it ?
How you can reduce voltage of a transformer?
Number of turns in the secondary winding define the voltage. Change the number of turn to change the voltage.
