  1. Electricity

  2. What is it?? • Movement of electrons from one atom to another • Trying to create a balance

  3. Three factors • Voltage • Pressure on the electrons. • Amps • Measurement of volume of flow. • Resistance • Resistance to flow.

  4. Just Like This Poor Sucker

  5. What does it take? • To make amps, circuit must be a loop • The more electrons moving means more work done • The more pressure (voltage) applied means more work done

  6. Measuring • Voltage • Live or dead circuit - whatever you want • Amps • Must be in ‘series’ in a live circuit • Resistance (Ohms) • Circuit MUST be dead

  7. Relationships • The three measurments all work together • One cannot change without affecting another

  8. Ohm’s Law • V = AxR • A = V / R • R = V / A V AXR
