  1. What is Ohm's Law?
    • Image Upload 2
    • describes the relationship between voltage, amperage and resistance in a simple electrical circuit.
  2. V or E
    • voltage - the amount of potential energy
    • Measured in volts
  3. if resistance remains the same...
    the current flow goes up or down if voltage goes up or down
  4. when resistance goes up...
    the current goes down (so long as the voltage remains the same)
  5. when resistance goes down...
    current goes up (if the voltage is still the same.)
  6. 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.
  7. I
    • current
    • measured in Amps (A)
  8. R
    • resistance
    • measured in Ohms ( Image Upload 4)
  9. P
    • Power
    • measured in watts (W)
