answer this please. thanks in advance!! please tel me                                                                 a christmas tree lights are set up in series
1. a set of lights has 50 bulbs  what will be the voltage across each bulb?
show your working out.

Sagot :

Presuming that this tree is connected into a mains power source in the UK. The total output of the UK mains source is 230V. So if we share this voltage equally between 50 bulbs:
[tex]230V \div 50 = 4.6V[/tex]

I'm not 100 per cent sure this is correct though and different countries may have different mains power supplies. Hope it helps anyway.

EDIT: This also does not take into account resistance in the bulbs and wires but is all I can tell you from the information provided in the question.

If 50 identical light bulbs are connected in series across
a single power source, then the voltage across each bulb
is ( 1/50 ) of the voltage delivered by the power source.
