What is Ohm's Law?

 describes the relationship between voltage, amperage and resistance in a simple electrical circuit.

V or E
 voltage  the amount of potential energy
 Measured in volts

if resistance remains the same...
the current flow goes up or down if voltage goes up or down

when resistance goes up...
the current goes down (so long as the voltage remains the same)

when resistance goes down...
current goes up (if the voltage is still the same.)

3 Truths of Ohm's Law
 * if resistance remains the same, the current flow goes up or down if voltage goes up or down
 * when resistance goes up, the current goes down so long as the voltage remains the same
 * and when resistance goes down, current goes up if the voltage is still the same.

I
 current
 measured in Amps (A)

R
 resistance
 measured in Ohms ( )

P
 Power
 measured in watts (W)
