1. OHM’S LAW

2. What is ohm’s law?
Ohm’s Law explains the relationship between voltage, current, and resistance
Used by electricians, automotive technicians, stereo installers, etc.

3. CURRENT
Current refers to the quantity of electrical flow.

4. VOLTAGE
It is the push or pressure behind current flow through a circuit.

5. RESISTANCE Ex: filaments in lamps
 Resistance is the material’s tendency to resist (go against) the current.
Ex: filaments in lamps

8. Voltage = current x resistance
Current = voltage
resistance
Resistance = voltage
