Electricity. What is it??. Movement of electrons from one atom to another Trying to create a balance. Three factors. Voltage Pressure on the electrons. Amps Measurement of volume of flow. Resistance Resistance to flow. Just Like This Poor Sucker. What does it take?.

What is it?? • Movement of electrons from one atom to another • Trying to create a balance
Three factors • Voltage • Pressure on the electrons. • Amps • Measurement of volume of flow. • Resistance • Resistance to flow.
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
Measuring • Voltage • Live or dead circuit - whatever you want • Amps • Must be in ‘series’ in a live circuit • Resistance (Ohms) • Circuit MUST be dead
Relationships • The three measurments all work together • One cannot change without affecting another
Ohm’s Law • V = AxR • A = V / R • R = V / A V AXR
