How many amps 7.5kw?

Answer 1

7.5kVA is a value derived from the voltage multiplied by the current.

Without knowing one, you cannot know the other.

For example, think of the number 10kVA

This could be made by :10kV * 1A or 5kV * 2A or 1kV * 10A or 2kV * 5A.

You couldn't possibly know which is the initial pair.

Answer 2

Watt= volts * amps

7000 Watts can be any combination there of:

At 120 volts it would be roughly 7000/120 = 58.33 amps

At 220 volts it would be roughly 7000/220 = 31.81 amps.

This is why 1000 watt power supplies for computers is getting near absurd. Typical home circuit is 20 amp and US power is at 120 volts so the max your going to draw before tripping a circuit is about 2400 watts.

Great lesson in converting watts/amps but, where is the answer to converting amps to KILOWATTS? Basically THAT was the question or did I miss something?

Answer 3

It depends on the voltage source in question.

watts = volts * volts / resistance

and

amps = volts / resistance

example 1:

Producing 7kW from a 120V source will require a resistor of size:

120V*120V/7000W = 2.05 Ohm

And this will pull 120V/2.05Ohm = 58.3 Amps of current.

example 2:

Producing 7kW from a 240V source will require a resistor of size:

240V*240V/7000W = 8.23 Ohm

And this will pull 240V/8.23Ohm = 29.2 Amps of current.

Answer 4

Depends on the voltage. Watts are volts x amps
