1. Series and parallel circuits

2. Learning goals We are learning to draw circuit diagrams.
We are learning the difference between series and parallel circuits.

3. Current electricity
charges (electrons) that move through an electrical circuit
uses:

4. circuit
must have a load, source and conducting wire

5. Circuit diagrams use symbols to show the components in a circuit
draw this chart please:
Component
Function
Symbol

6. wire
conductor
allows electrons to flow

7. Cell, battery electrical source longer side is the positive terminal
shorter side is the negative terminal

8. Lamp (light bulb) specific load
converts electrical energy to light and heat

9. resistor
general load
converts electricity to heat

10. switch
opens and closes the circuit

11. ammeter
measures current through a device
connected in series

12. voltmeter
measures voltage across a device
connected in parallel

13. rules use the correct symbol
use a ruler for straight lines, 90° angles
label + and – on energy source
label direction of current flow (charges moves from the negative terminal of the power source to the positive terminal)

14. Series circuit
an electric circuit in which the components are arranged one after another in series
only one path along which electrons can flow

15. Parallel circuit
an electric circuit in which the parts are arranged so that electrons can flow along more than one path
each component has its own path for current

16. Try this
Draw a circuit diagram of a series circuit with a battery, connecting wires, and one light bulb.
Draw a circuit diagram of a parallel circuit with a battery, connecting wires, and two light bulbs.
