Electrical Fundamentals Flashcards
Voltage compares to what and I gas system
Pressure in a gas or liquid system
Voltage
Difference of potential, electro motive force, ability to do work
Symbol
E or V (this symbol will be used in the ohms law formula)
Current can be defined as
The flow of electrons
Unit of measure
Ampere
Symbol
I
Current compares to gas flow
In a gas system The pressure causes the gas to flow in the pipe just as voltage caused electrons to flow in an electrical circuit
Resistance can be defined
The opposition to current flow
The measure for resistance is
Ohm, symbol for a home is R, also the Greek letter omega
In a gas piping system resistance can be compared to
The orifice of fact or the restriction to flow provided by the inside diameter of the pipe
Voltage can be defined as
Difference of potential
