Those numbers describe the power used by the two bulbs, in other words how many joules of electrical energy they use per second. The 100 watt bulb uses 40 watts more.
60 Watts is the amount of electrical power the bulb uses when it is switched on.
400
Yes if it is a 12 volt DC bulb.
If you used them simultaneously, probably around 1.46 million 60Watt bulbs.
28.7 c
Yes you can.
Power = Current * Voltage Current = Power / Voltage Current = 60 W / 120 V Curretn = 0.5 A
About as much as 15 typical (60watt each) light bulbs together. Or expressed in horsepower: about 1.2Hp Mains volts and ampere: 230 volt at 3.91 ampere = 900watt 110 volt at 8.18 ampere = 900watt
It is not recommended to upgrade the bulb wattage in a projector as it may cause overheating and damage the internal components. Stick to the manufacturer's recommended wattage for the best performance and safety.
Under the right circumstances, yes. So will, for example, a 15 watt soldering iron. It just won't melt very much. It is not the wattage that determines the temperature, it is the insulation (or lack thereof) around the bulb and chocolate that determine it.
A 60 watt bulb, left burning for 8 hours a day and powered by electricity from a coal fired generating plant will be responsible for slightly less than 50 kg/mon of CO2 emissions.
no because it would blow up because the socket would draw 13 watt not 9 watt
