Need the voltage or current of the circuit. And the type of lamp (bulb)--is it incandescent, fluorescent, LED, discharge?
Also need to know the temperature--the resistance of a tungsten filament changes by a very large amount from ambient temperature to hot/operating temperature.

∙ 10y agoAn Ohm is a unit of resistance. A Watt is a unit of power. The two cannot be equated.

It depends on the voltage, the answer is the voltage-squared, divided by the resistance in ohms.

1 watt is equal to 1 volt times 1 amp.

How many watts of electricity equal to a quantum?
100 watts
Which has a least resistance 220 volts 100 watts or 115 volts 100 watts?
The higher voltage need more resistance, from the formula W = V2 / R. That means R = V2 / W. So 220 v 100 W is 484 ohms, while 115 v 100 W is 132¼ ohms.
How many horsepower are in a 100 watt light bulb - 1.3?

What is the impedance of a series circuit containing a resistor of 100 ohms and an inductor with an Xl equal to 80 ohms?

What equals 100 watts?
That depends what you want to convert it to. Watt is a unit of power. 100 watts is equal to:0.1 kilowatts100 joules/second
How many watts are in 100 microwatts?
.0001 watts
If you have two 150 RMS watt subs on the same ch of an amp What is the RMS watts needed from the amp?
Depends on the impedance of each speaker. If they are car subs and not converted home speakers, they are probably 4 Ohms each. Depending on how you wire them you get either 8 Ohms or 2 Ohms. 8 Ohms is not a problem load-wise for the amp, but if it is rated at 100 watts into 4 Ohms, then you will only get 50 watts into 8. Many car subs nowadays will handle a 2-Ohm load, but some will not. Your two speakers will handle 2x150 watts or 300 watts. An amp that is rated to drive 300 watts into 4 ohms will either deliver more like 500 watts into 2 Ohms, or it will melt through the floor of your car. So you need to look up the specs for your amp in the instruction manual. If it will only run into a 4-Ohm load, you can only use one 4-Ohm sub per channel. If it will handle a 2-Ohm load, you will have to turn it up slowly or you will blow your speakers out. Mr Ohm and his law will not be denied.

How much electrical resistance does a big city have?
The resistance is simply the value of resistances of all electrical equipment connected in Parallel by all consumers in a big city.The answer is amazingly accurate, if we have the average power consumption (Megawatts-MW) figure from the power company at any time of the day.Suppose a big city is consuming 100-MW at a given time. Assuming we use 100 volts AC at consumer homes, then at any given moment the instantaneous resistance (R in ohms) of the city is simply given by the formula:Power(watts) = (Volts x Volts) / Resistance (R in ohms)..........or,P=V2/ R, therefore,R = V2/P (ohms)......... then,If:V=100 volts (ac)P= 100,000,000 wattsThen:R = 100 x 100 / 100,000,000 = 0.0001 (ohms)(make sure to use only watts, volts and ohms in the formula above).Good Luck !The resistance is simply the value of resistances of all electrical equipment connected in Parallel by all consumers in a big city.The answer is amazingly accurate, if we have the average power consumption (Megawatts-MW) figure from the power company at any time of the day.Suppose a big city is consuming 100-MW at a given time.
