All you can do is get in the ballpark knowing resistance of windings and the supply voltage. Current = Voltage divided by resistance.
Wattage = voltage x current x power factor. For a motor the power factor is between zero and sone number less than one, with one being just a resistive load. So if you calculate the current and use a PF = 1 you can get worse case wattage.
Hot resistance is your total resistance you can have with out exceeding your wattage limit
Resistance is resistance , no matter if it is contact resistance or any other resistance. And formula is R = V / I.
The formula you are looking for is I = W/E.
The resistance force multiplied by the resistance distance.
rotor contactor are used to cut the resistance in slip-ring motor connected through resistance box. resistance is proportional to torque. so by controlling rotor contactor resistance can be controlled and hence torque can be controlled. for more information check torque and speed characteristic of wound motor.

Hot resistance is your total resistance you can have with out exceeding your wattage limit
Yes. The resistance of a globe depends not only on the wattage of it but also on the voltage. A 12 V Globe would has a quarter the resistance of a 24 volt globe for the same wattage. (when alight)
Wattage, you mean power. Power = V * I. V - the voltage and I the current.
You need to find the wattage of the pump motor. This is found by multiplying the voltage of the motor by the amperage of the motor. Once you have this figure use it to find an inverter that can handle this wattage load at a 240 volt output.
Devide the wattage by the voltage
No, the highest wattage bulb will have the lowest resistance.
The resistance of a motor winding is expressed in
For calculation purposes one horsepower is equal to 746 watts. So to find the total wattage of the motor multiply the total horsepower by 746. To change the wattage to kilowatts divide the total wattage by 1000.
Resistance. Water has a lot of resistance.
Because Heat is Directly Proportional to Resistance Of ElementAnswerPower is inversely, not directly, proportional to the resistance of a heating element.So, the higher the resistance, the lower the heating effect. For example, a 'high-wattage' lamp has a lower resistance than a 'low-wattage' lamp.This is because power is equal to the voltage squared divided by resistance; so, the lower the resistance, the more powerful (and, therefore, the hotter) the heating element.
Most equate wattage with the amount of light a bulb will put out. But, the wattage is the result of the resistance of the element and the voltage and is the amount of heat. the frequency is unrelated.
