two bulbs of 100w and 40w respectively connected in paralel
across a 230v supply.which bulb will glow bright and why?
Answer Posted / sarmadahmed
Bulbs have filament and its light depends on how hot the filament is. The greater the current, the hotter will be the filament, and the brighter will the bulb lit.
Since both the bulbs are connected in parallel, the voltage across them will be equal, 100 watt bulb will have (100/230)= 0.435 amp of current while 40 watt bulb will have (40/230) = 0.174 amp of current passing through it. Hence 100 watt bulb will be brighter.
