4000 watt generator equals how many amps

A 4000 watt generator has a power of 4000 watt,

 In physics a power can be calculaled using this formular

P=IV

 Where p is the power, I is the current and V is the voltage.

 THEREFORE  a 4000 watt generator will likely have a power of

P=IV

Our mains supply is usually supplied at 110 volt or 220volt in some  states,

It is only in Australia that the mains supply is around 230volt.

 But here we are talking of 4000 watt generator, therefore we are going to consider the output voltage of the generator.so what is important here is know the voltage of the  4000 watt generator.

 A 4000 watt generator can have different voltage,

Let us consider some elected gen,

A sportsmen 4000watt generator has a voltage of 120 volt,

For this generator

 The amp can be calucaltd as folows

Which is same as

400 = amps  * 120

 Iamps =4000/120

Amps =33.33 amps
