In the United States it takes at least 110 volts of alternating current. To get rated luminous output from lamp, if you connect 2 lamps in series, you need voltage equal to twice the lamp's voltage rating and if lamps connected in Parallel, you need voltage equal to lamp's voltage rating.

∙ 12y agothe two bulbs in a series circuit would shine according to the respective powers.
But here the bulb with higher power would glow with lesser intensity than that of with lower power.this is because power for a given bulb is rated at constant voltage so power =v^2/R.
but here in series circuit power becomes i^2 *R because here i is constant so i across each element is same so one with lower resistance glows dimmer than higher resistance one.

∙ 16y agoas long as the bulbs are the same power then the voltage will be split between them ie a 9v battery would split 4.5v to one bulb and 4.5v to the other.

∙ 14y agothe bulb will get duller because the electricity is sharing its power into the 2 bulbs joined onto the circuit that is what you will find will happen well only if you do it right

∙ 15y agoIt will be same

How many amps do 8 40 watt fluorescent lights take?
It depends on the voltage and whether the lamps are actually 40 watts or 40 watt equivalent. Watts / volts = amps
How many volts does it take to power a big light bulb?
For lighting up a city you need 120 volts in the USA and 230 volts in Europe. It's just the usual voltage the light bulbs are needing.
How many volts does it it take to arc 0.5cm?
Just a little over 3,000 volts
Why does a wall switch 'crackle' and the light flicker?
There is a high current draw on the circuit and the switch is getting old. Change out the switch, see if you can find a 20 amp switch as the internal contacts are designed to take the higher amperage. Check how many lamps are in the circuit in watts, add them together and use the formula for amps. Amps = Watts/Volts (120).
Why sodium vapuor lamps are used as street lights instead of simple white tube lights?
High pressure sodium lamps take a while to fully light up, however they are very energy efficient and save the council money.
How many volts does it take to light up a car light bule?
6 volts
How many amps to the fog lamps for an 01 Chevy S10 take?
depend's on the light's.. 5-15 amp's..
How many Indians does it take to change a light bulb?
None. The white man came and took all of their lamps.

What did the light bulb take place of?
candles, gas lights, and oil lamps
How many volts does a iPhone charger take?
4.5~5.3

How many volts does it take to run a fuel pump on a 2000 s10?
12 volts DC.
Are there any table lamps out there that only take energy efficient light bulbs?
I have not ever seen a table lamp that only requires a energy effcient light bulb. Usually all lamps will accept any light bulb regardless or energy wattage or usuage.
What kind of amps does a 65 watt light take?
amps equals watts divided by volts.
