Lesson 2: Series Circuit
Learning Objective: 1. Create a series circuit.
2. Observe what affects a series circuit
What is a Series?
circuit diagram
cell switch
lamp
wires
Scientists usually draw electric circuits using symbols;Draw the series circuit, this is your guide to refer back to.
1. Create your own series circuit with one light bulb.
2. Observe what happens as you add in up to 4 more light bulbs.
3. Create a table to record the observations
4. Answer the following questions:O What happens to the brightness of the bulbs as
you add more?O Try to explain what happens to the brightness of
the bulbs when you add more bulbs to the circuit
# of light bulbs ?
AdvantagesYou can add more power sources, like batteries, and increase the force of the output = more power (ie brighter lights)
Disadvantages1. It is impossible to control the bulbs
individually.
2. The more output devices (ie lightbulbs) you add the slower the current becomes as there is more resistance in the circuit. Ex The more light bulbs = dimmer lights.
3. If a bulb were broken or the pathway broken in any way, the other bulbs would go out too
What if all circuits were in series?
I'm off to bed but my sister wants to stay up and watch TV
The bulb has blown inthe lounge lights andI need to find areplacement
I'm having a party andI want a long string oflights on the wall
My rear light has goneout on my car andI'm driving on themotorway at night
