How do you calculate power when you know the voltage and the frequency?

Power is equal to the product of voltage and current, frequency has no relationship with voltage and power, 220V voltage, 1 square copper wire can pass 10 amperes of current, or with 2 kilowatts of load, the load capacity of the wire is not proportional to the cross section, not the relationship between 10 square and 100. Power does not have much to do with frequency,P=UI,P=U2\/T. Only know that the voltage is not enough, China's household appliances are voltage 220V, frequency 50 Hz, different electrical power is different.


Power = voltage times current... You can't figure out the frequency... Frequency means the number of times alternating current changes in a second... It has nothing to do with power...
