parallel circuit

a closed electrical circuit in which the current is divided into two or more paths and then returns via a common path to complete the circuit .
Big image

series circuit

Where there is only one path from the source through all of the loads and back to the source.

voltage

an electromotive force or potential difference expressed in volts.

resistance

The force that appose the flow of electron current in a conductor.

resistor

Test 1

IV: parallel DV: Light


Hypothesis 1 : If the Christmas lights are arranged in a parallel circuit then when 1 bulb bursts (is removed) the other bulbs DON'T light up.


Observations 1 : the wire and the battery

Test 2

IV: parallel DV: light



Hypothesis 2 : If the Christmas lights are arranged in a parallel circuit then when 1 bulb bursts ( is removed) the other bulbs STILL lit up.


Observations : wire and battery

conclusion

a parallel circuit is the best series to use for Christmas lights because if one bulb bursts out they will still work.
