1 horsepower = 746 watts
2 hp = 1,492 watts
Voltage x current = power
230 x current = 1,492
Current = 1,492/230 = 6.487 Amperes (rounded)
The resistance of the circuit will be 46 ohms
Take the KVA and divide it by the voltage. 25/.230 = 109 amps. The transformer can put out up to 50% more that its rated for short durations. So you could get around 150 amps out of a 25 Kva tranformer in a worst case situation.
You are working with two different values. Watts is the product of amps times volts. W = A x V, as you can see if there is a value missing then there can be no answer given.
A source of 208 volts can be obtained from any two legs of a three phase four wire 208 volt system. The two legs are classed as single phase 208 volts. The lead tags can be L1-L2, L2-L3, or L3-L1 all of which will give you 208 volts. Any of these lead tags to the grounded star point (wye) will give you 120 volts.
If you had 230 volts on each legs of a power supply that would be true but it is more likely that you are dealing with a circuit that has 115 volts on each leg and the total is 230 volts across both legs. The Power meter on your house supply line will measure and record all aspects of the currents being supplied to the breaker panel.

The maximum single phase HP motor listed in the CEC is 10 HP. At 115 volts 100 amps and 230 volts 50 amps.
For a single phase 3 HP motor at 208 volts the amperage is 18.7 amps. For a three phase 3 HP motor at 208 volts the amperage is 10.5 amps. This figure is derived at by taking the full load amps at 230 volts and adding 10%. As the voltage goes down the amperage goes up. For 200 volt motors 15% is added to the FLA of a 230 volt motor.

Watts = Amps x Volts Amps = Watts / Volts you only need to know two of the three to work out the other so 230 volts at 10 amps gives 2300 Watts (2.3 kW) 2.3kW at 230 volts draws 10 Amps
208-230 Volts 1/3 Phase 60 Cycles Breaker Size 50 / 40 Amps Run Amps 39/31
Watts = Volts x Amps x Power Factor Maximum Power Factor is 1 for resistive load.
Watts = Amps X Volts Grab your calculator!
I(per Phase)=4000/(230*3) = 5.8A
In normal simple circuits WATTS = VOLTS x AMPS So if you use a 12V car battery 4 amps is 48 Watts American 110V mains 4 amps = 440 Watts English 240V mains 4 amps = 960 Watts
9000 BTU/hour is equivalent to 2300 watts so the heater will draw 10 amps on 230 volts.
