Answer / sanjay d dalvi

CFL bulbs have an electronic circuit in the base of the
bulb. This electronic circuit is called an electronic
ballast. There is an electronic oscillator and a minature
transformer that produces high voltage enough to ionize the
gas in the tube, initially.

PL tubes are simply connected to the pins at the base.
External ballasts must be used to supply the high voltage
necessary to start the lamps.

Hi frnds :) plz tell me that i have 100 KVA 3 phase generator so by thumb rule 100*1.4 = 144 amps and generaly we can operate at 80% load...so it will 144*0.8 =112 amps.... so now i m confused about single phase load.....if we use that generator only for single phase the that 112 amps is total single phase load or i can give 112 amps at red 112 amps at yellow and 112 amps at blue.... i mean that total single phase load that 100 KVA generator will take is 112+112+112=336 amp ??
