Question
In an electrical circuit three incandescent bulbs A, B and C ofrating 40 W, 60 W and 100 W are connected in parallel to anelectric source. Which of the following is likely to happen regardingtheir brightness?
Solution
The brightness of an incandescent bulb is determined by its power rating. The higher the power rating, the brighter the bulb.
In a parallel circuit, each bulb is independently connected to the power source. This means that each bulb will draw power according to its rating, regardless of the other bulbs in the circuit.
Therefore, in this case, bulb C with a power rating of 100W will be the brightest, followed by bulb B with a power rating of 60W, and then bulb A with a power rating of 40W.
