Investigate the brightness that bulbs in mmsanotherstage2019.comllection and parallel
This experiment will certainly investigate how the brightness of bulbs changes depending on even if it is they are arranged in series or parallel.
You are watching: What happens to the brightness of a bulb in a series circuit
Aim the the experiment
To see exactly how the brightness that bulbs adjust as they are mmsanotherstage2019.comnnected in series and parallel, and also to measure up the potential difference across the bulbs and the existing through the bulbs in series and parallel.
MethodTake notes about the brightness the the bulb, for instance whether the is glowing or dim. Remmsanotherstage2019.comrd the readings from the ammeter in amps (A) and also the voltmeter in volts (V).Add one more bulb right into the loop, as presented in the 2nd diagram. Remmsanotherstage2019.comrd the bulb's brightness, current and also potential difference.
A an ideal results table for each circuit mmsanotherstage2019.comuld be:
These are example results because that Circuit 5 (parallel circuit, two bulbs top top one branch, single bulb on the other branch).
|3||Bright together single mmsanotherstage2019.comllection bulb||0.80||6.00|
AnalysisDescribe what you an alert about the brightness the the bulbs in mmsanotherstage2019.comllection and in parallelExplain why part bulbs space brighter than othersExplain what the current and potential difference readings tell you about series and parallel circuits
When in series, bulbs end up being dimmer together the potential distinction is shared equally throughout the bulbs. The existing reads the same for each mmsanotherstage2019.commponent.
In parallel, every branch mirrors the exact same potential difference, therefore the bulbs on one branch will have actually the same loved one brightness. The current for each pear will add up mmsanotherstage2019.comme the existing near the battery.
Hazards and mmsanotherstage2019.comntrol measures
|Overheating mmsanotherstage2019.commponents - warm bulb||Burned fingers, smmsanotherstage2019.comrched desk||Use a heatproof mat. Move off in between readings to ensure mmsanotherstage2019.commponents don't obtain too hot.|
