The 220 V lighting circuit is connected with 10 60 W incandescent lamps, 10 40 W fluorescent lamps, 10 trial calculation branch I and circuit I (fluorescent lamp P factor is 0.5, ballast active power P loss is 8 W)

The 220 V lighting circuit is connected with 10 60 W incandescent lamps, 10 40 W fluorescent lamps, 10 trial calculation branch I and circuit I (fluorescent lamp P factor is 0.5, ballast active power P loss is 8 W)

60w*10=600w.600/220v=2.73A
40w*10=400w .400/0.5=800w.800w+(10*8w)=880w,880/220v=4A
Total circuit current = 2.73 + 4 = 6.3A

What is the difference between incandescent lamp, tungsten lamp and fluorescent lamp?

Incandescent lamps also use tungsten filament, so there is no essential difference between incandescent lamps and tungsten filament lamps. Ordinary incandescent lamps are filled with nitrogen. Some small tungsten filament lamps are filled with halogen gas, such as iodine. These lamps are called halogen lamps and have a long service life. Some of them are often used in car direction lamps. Incandescent lamps and halogen lamps both use white heat principle to emit light and
