Answer Posted / dinesh dafare
40 w bulb is high resistance approximately 1322 ohms and
100 e bulb is low resistance approximately 529 ohms .
Hence in series circuit voltage divide and current same.
Hence current required to 40 w is less than 100w so 40 w bulb is brighter

I have an existing old MCCB. ABB Model SACE, the rating are: Ue = 660 volts, Iu =1250 Amps, 3 poles, Ith (max) =800 amps at 45 deg C. I need a circuit breaker for my 3 phase motors, 380 volts 60 hz. the supplier required the minimum ampacity of the breaker to be 911 amps. can i use this breaker with rating of Iu =1250 amps but Ith = 800amps maximum?
