No.
The watt is the unit of power. For electricity, watts = volts x amps.
If the appliance tells you how many watts it's supposed to use you can buy a watt-meter to measure how many watts the appliance is using buy plugging in the meter into the wall and then plugging the appliance into the meter. A popular brand is "Kill A Watt", it meter can be bought on E-bay for under $25.

Amps (current) times volts = watts. so watts divided by volts = current (Amps). i.e.- 0.5 Amps.

Wire sizes and ampacity are regulated by code. # 14 wire 15 amps, #12 wire 20 amps, #10 wire 30 amps, #8 wire 40 amps, #6 wire 60 amps. These are the most common, a slight variation in amperage depending on the insulation factor.
If it is a 32-amp circuit you can use any appliance that takes less than 32 amps. That includes a 15-amp appliance. All appliances fed from that circuit must use 32 amps or less in total.
The total amps on the circuit exceeds 15 amps. It is possible your appliance is drawing more than 15 amps, but more likely that there are other things on the circuit causing the total current to be exceeded.
The equation for wattage is W = A x V. Substitute your values into this equation and you will have your answer.
Answer for USA, Canada and countries running a 60 Hz supply service.No. Even though 240 volts uses two breakers it is still classed as a single phase service. Kirchhoff's law states that current entering a circuit is equal to current leaving the circuit. Since the appliance draws 10 amps, the whole circuit has 10 amps flowing through it.
The formula is Resistance= Voltage/ Amps(current) In your example: R=50/2.5, so the answer is 20 ohms.
