Series and parallel circuits Lab
Part A: Series
The bulb will light up pretty bright
The 2 bulbs will be a little dimmer because they don't have as much power
Not as strong
The 3 bulbs will be even dimmer
3, 1 unscrewed
The whole circuit will shut off because there will be nowhere else for the current to pass
The whole circuit shut off
Part B: Parallel
They will both light up
They both lit up
They will all light up but a bit dimmer
They lit up but dimmer
3, 1 unscrewed
Only 1 will go off because it's a parallel circuit
1 light went off
Part C: pg. 288 Q. 2-6 (both sets)
2. Series Circuit - The brightness of the bulbs changes when you add more bulbs because the current in series passes from one bulb to another and the power gets lesser as it passes from bulb to bulb.
This is because the power has to be distributed between each bulb on the same path and each bulb you pass adds resistance.
Parallel Circuit - The brightness of the bulbs doesn't change because each bulb in on its separate path thus getting the same power as the others. There is no added resistance.
3. Series Circuit - The circuit shut off because there is only one path for the current to go through and when the light bulb is unscrewed the circuit breaks.
Parallel - Only the one light bulb shut off because each bulb has its separate path on a parallel circuit making it so one light bulb being unscrewed doesn't affect the others.
4. Series Circuit - If you kept adding light bulbs to a...
