What current is drawn by a 100 W light bulb on a 110 V household circuit?
A 100 Watts bulb draws 0.90 Amps.
How much current does a 60w lamp draw when connected to 120V?
In fact, the 120-Watt bulb would have a current of 1 Amp and a resistance of 120 Ω; the 60-Watt bulb would have a current of 0.5 Amp and a resistance of 240 Ω.
What is the power rating of a device that draws 0.8 a when connected to 120V?
What is the power rating of a device that draws 0.8 A when connected to 120 V? 36 W. A pair of 60-W and 100-W incandescent lamps are intended for 120-V operation.
What is brighter 60w or 100w?
When both bulbs are connected to the rated voltage, they will dissipate the rated power. The brightness of a bulb depends on the power it dissipates, so the 100 W bulb will be brighter than the 60 W bulb. The 100 W bulb has a smaller resistance, so it will be the brighter bulb.
How much current does a 100 W lamp draw when connected 120V?
or current=100/120=0.833 amperes.
How many 100w light bulbs connect to 120V?
The current drawn by 100 watts incandescent lamp is equal to 100/110=0.90 Amps. About 1 amp current must be reduced by removing one bulb. Total 15 bulbs can be safely operated.
Which draws more current a 60 W or 100 W incandescent lamp both rated for 120 V operation?
A 60-W bulb and a 100-W bulb are connected in series in a circuit. Which draws more current? Which draws more current when connected in parallel? 60W draws more current in a series, both are equal.
Which has the thicker lamp filament a 60 W incandescent bulb or a 100 W incandescent bulb?
Hence, 100 W bulb filament is thicker than that of 60 Wbulb .
How do I calculate power consumption of 12V?
The 12 volt system you have is rated at 0.2 amps at 12 volts. Multiply the amps by the hours and you get the result of 1.2 amp-hours per day. You use three 20 watt 12 volt lights for about four hours each night. The power consumption for each light we worked out earlier to be 1.67 amps.
