I've always wondered what the relationship was between volts, amps, watts, ect. 110V I know quite well !!! Is there equivelants between them or are they all separate units of elictrical measuremnets of different types of circutry? thanks

It's as easy as PIE. P = IE. Power (watts) = Intensity (amps) times Electromotive force (volts). The full acronym is referenced by the PIRE chart where R = Resistance in ohms. To confuse things there is also mho.

Watts = Amps X Volts
A device drawing 10 amps at 110 volts = 1100 watts, or 1.1 kw (kilowatt). Run that device for an hour, and your electric bill will show you've used 1.1 kwh (kilowatt-hour).
You can use the same equation to find any missing piece. For example, your household current it 110 V, and your hair dryer says it's 1500 Watts - divide 1500 by 110, and you know your dryer draws 13.6 amps. Useful for seeing if you might be overloading a circuit, since fuses and breakers are rated in amps. Remember that the stove, water heater, and some other items are generally 220 V, so use that in your calculations.

They measure different types of things (the type of circuitry is not really important). I'll explain them in terms of the movement of electrons, which after all is pretty much what an electric current is.
Amps (current) - measures how many electrons per second ae passing through a particular point or component. More properly, amperes specifically measure how much total charge, in Coulombs, is passing through a given point per second.
Volts (potential difference) - measures the difference in electrical potential between two points. Think of this as representing the amount of energy used up per unit charge in going from one point to the other.
Watts (power) - the product of the above two, at any particular instant; it measures how much total energy (in Joules) is being used per second. It obviously makes sense that this would be the product of the amount of charge going through the circuit per second and the amount of energy used per unit charge.

The link below will give you a detailed explanation. There is no sense in my pasting it here. I hope the water analogy is helpful.

they are all different units. volts is for voltage. amps or amperes is for current and watts or wattages is for electirc power.

All are interrelated
V=Volts
A=amps
R=resistance ohms
P=Power watts
V
=A*R
P
=V*A
=A^2*R
