How many amps will a 260 ohms resistor on a 120 volt circuit use?
Just use Ohm's Law Voltage = Current x Resistance Amps = Voltage Divided By Resistance Amps = 120 / 260
Can you run fan on dc?
If you mean by that a normal home ceiling fan, No, you can't. Because it is an AC motor inside that. If you use fans using DC motors ,motors like the ones used in many toys for example or the ones used inside the earlier cassette or vcr tape drives, yes ,you can use DC.
How much electrical energy does electric fan with a power rating of 100 watts use in 1 hour?
It varies tremendously depending upon the size of the fan and the power of the motor. The best way to answer your question would probably be to look at the back of the fan, or on the bottom. It usually will tell how many watts the fan draws. If it only tell amps and volts, remember that watts = amps X volts. Remember that watts does not have a time component; so to say that it draws a certain number of watts in an hour is not correct. You should rather ask, "How many watt-hours does it consume in an hour?" That is the number of watts times the number of hours that it drew that number of watts.
Problem this fan draws 30 amps for an instant to start then settles to 10 amps Can a capacitor be used in line to take the load off the switch and provide the extra amps needed to start the fan?
Not really, unless you have a capacitor start type of motor. Capacitors can be very hazardous if improperly connected to mains power and I wouldn't suggest your trying it if you're not experienced or qualified. Best bet is just to get a heavier swicth or use a heavy duty switching relay.
How many amps does a 50 horse power electric motor use?
Need to know the voltage of the motor.
