1. Electric Current

2. Current- flow of electrons through a wire or any conductor.
Potential difference (voltage)- the difference in potential between two different places.
Resistance- the tendency for a material to oppose the flow of electrons, changing electrical energy into thermal energy & light.

3. Ohm’s Law- states that potential difference equals current times the resistance.
-All conductors have some resistance.

4. Ohm’s Law equation
Variable Ending Units
Voltage (V) volts
Current (I) amps
Resistance (R) ohms or Ω

5. V = I x R
I = V / R
R = V / I V . . R I x
