Ohm's Law
Ohm's Law is the primary and fundimental rule in electricity & electronics.
In electricity 3 main properties exist: Voltage (V) Current (I) Resistance (R) If you know any two properties, the third can be calculated by using Ohm's law. V = I x R I = V divided by R R = V divided by I --------------------------------------- A 'Watt' is the unit of electrical power. It can be calculated by the following: W = V x I W = (V x V) divided by R W = (I x I) divided by R Note: English notation (W & V). For American notation, substitute: W = P (Power) V = E (EMF) [Electro Motive Force]

Re: Ohm's Law
Quote:
since V = I x R & W = V x I then W = NOT (I x I) divided by R but W=(I x I) x R you can delete this notice after making your alterations  or maybe not ... revenge on a shooting gallery incident perhaps ...
