1. Circuits & Voltage

2. Continuing with Circuit Lab…
Continue building your circuits and getting your readings for the circuit lab.
REMEMBER:
Set the multimeter to 200m DCA
Set the multimeter up in series

3. What does the
Battery do to
The circuit?
What does the
Lightbulb do to
The circuit?
What does the
wire do to
The circuit?

4. What are the
Differences
Between these
Circuits?

5. What are the
Differences
Between these
Circuits?

6. What are the
Differences
Between these
Circuits?

7. A Circuit as a String Activity
What was the battery? What was the lightbulb?
How was current represented?
How was voltage represented?

9. So…what are volts???
Volts are a measure of how much energy is being supplied to the circuit
Voltage is measured in VOLTS
Energy is measured in JOULES
1 volt = 1 joule per Coulomb of charge

10. So what do you measure them with?
Volts are measured with a voltmeter (also available on a multimeter)
Voltmeters must be connect in PARALLEL
