100w bulb will glow with more brightness due to parallel
connection.

Answer / ahatesham

Obviously 100W bulb will glow brighter because voltage
across both bulbs are same but current flowing through 100W
bulb will be more compared to 40W and power of 100W bulb
will b more.

Answer / 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.

Answer / shivam

Both Bulb is glow Bright Same,Because it connected in paralel.

bit confused - am i correct in thinking that to determine line to line voltage in a star config 110v 3 phase 4 wire distribution system i would use a voltmeter? I have a circuit configured as an unbalanced load, consisting of three incandescent lamps (1x40w, 1x60w, 1x100w - all 110v rated)connected in a star configuration to a 110v 3 phase 4 wire distribution system. I want to find out what types of meters i would use to obtain: a) each line to line voltage b) the line to neutral voltage across each load c) current flowing in each line and load d) current flowing in the neutral conductor e) power supplied to the loads im assuming i would be using ammeters in series along each line and voltmeters in parallel across each line to neutral? Also how could i predict these meter readings before taking them and with which formulae? Any help would be greatly appreciated A.
