3. CBC Auto Tech Atomic Structure n Non-conductor n Semi Conductor n Conductor –Levels of

4. CBC Auto Tech Capacitance n What is it n Where is it used P 26

5. CBC Auto Tech EMF

6. Ohm’s Law V = AxR V = IxR V = IxO All the same V A x R P 24

7. CBC Auto Tech Ohm’s Law n V = AxR n A = V / R n R = V / A

8. CBC Auto Tech Ohm’s Law n Circuit Boards –Create the same simple light bulb circuit –Measure the battery voltage with the light bulb on. –Measure the precise battery voltage with the light bulb on. –Measure the precise amperage in two places –What is the resistance for the circuit

9. CBC Auto Tech Use ohm’s law to figure the resistance n Add the 10 ohm resister at the switch n use ohm’s law to figure current. n use ohm’s law to figure volts lost at: –the resister –the bulb n Figure total n Then prove with your meter

10. CBC Auto Tech Ground side n Add a second resister (15 ohm) in the middle of the ground side n use ohm’s law to figure volts lost at: –the 10 resister –the bulb –the 15 ohm resister n Figure total (volts lost) n Then prove with your meter
