Andre Ampere didn't 'invent' the ampere. The unit for current was named many years after the death of Ampere, in his honour. The ampere is defined in terms of its magnetic effect -i.e. the resulting force between two, parallel, current-carrying conductors. It was Ampere who discovered the relationship between current and force.
That's like asking how many meters in a liter. Ampere and Volt are two DIFFERENT measurements. Ampere is how much electricity you are using, while volts are how much pressure the electricity is under(Think water). If you want to figure out how many amperes your appliance is using you could use this formula: P=UxI (Watt=Volt x Ampere) or U=RxI(Volt=Resistance x Ampere).
No-one 'invented' the ampere. It was named as the unit of electric current, many years after the death of the scientist by that name.
Depends on the number of phases.single phase uses 4 diodesthree phase uses 6 diodes
To answer this question a voltage and pf (power factor) must be stated. kW = I x E x pf/1000.
It depends on the voltage and whether it is a single- or three-phase load.
10mm = 1cm 50mm = 5cm
An object that measures 50mm is equal to 5 centimeters (1cm = 10mm).
0.050m
The power factor is only taken into consideration when the Kilowatts of a transformer is used.

A single-phase cable will have a line and a neutral conductor and, possibly, but not necessarily, an earth (ground) conductor. A high-voltage three-phase cable will have three line conductors. A low-voltage three-phase cable is likely to have three line conductors and a neutral conductor.
Oh, dude, it's like basic math time! So, there are 10mm in a cm, right? And if you divide 50mm by 10mm, you get 5. So, there are 5 50mm in a cm. Easy peasy, lemon squeezy!
