1. Circuits

2. Drawing a Circuit
Draw a circuit that contains one battery and one working light bulb

3. Schematic Diagram

4. Single Cell Battery Battery or EMF
The longer side is the positive terminal
The shorter side is the negative terminal
Every Circuit must have at least one of these!
Battery or EMF

5. Resistor
40 Ω
The resistance is usually written above the resistor

6. Light Bulb
Since a light bulb is also a type of resistor, it can also be drawn using the resistor symbol

7. Capacitor
Looks like the parallel plate capacitor we saw in the capacitance notes!

8. Connecting Wire
A straight line is drawn to represent the wire connecting any two components in a circuit

9. Switches
Open: Current Cannot flow
Closed: Current can flow

10. Meters V A Voltmeter: Ammeter:
Must be connected OUTSIDE of the circuit
Usually on either side of a resistor V
Ammeter:
Must be connected WITHIN the circuit A

11. Try One!
A circuit that contains one battery one switch and two resistors, with an ammeter measuring the current through the entire circuit
With a voltmeter measuring the voltage across one of the resistors
