A typical domestic water heater uses 3 kW. On a European 230 v system it would use 13 amps.
Watts = Amps x Volts for a resistive load like a water heater.
The electric heater will have power rated in Watts. The Amps it will draw depends on the voltage system you are using. Can be calculated by formula I (Amps) = P / V In the USA with 110V system a 2400W heater will draw 2400 Watts / 110 Volts = 21.8 Amps In Australia with a 230 V system a 2400W heater will draw 2400 Watts / 230 Volts = 10.4 Amps
The heater with 750 watts and 7.1 amps is less expensive to run. This is because it has a lower amperage, meaning it requires less electric current to operate. The 600-watt heater with 12.5 amps requires a higher electric current, which could translate to higher electricity costs.

46 amps
The formula you are looking for is I = E/R. Amps = Volts/Resistance.

None.
Likely one of the two electric elements is going out which creates very high resistance in the circuit and therefore draws very high current (amps) and causes the breaker to trip.
Watts= rate of using energy Amps= current flow Think of it as a bucket of water with a hole in it. Watts is the amount of water leaking from the bucket (1 gallon) Amps is the size of the hole ( it took 3 minutes for that 1 gallon to leak out of the bucket)
The GE water heater SE50M12AA01 is a 5500 watts or 5.5 Kilowatts water tank. The amperage on such a tank is I = W/E. Amps = Watts/Volts. Since most hot water tanks in North America use a voltage of 240, the amps will be 22.9 amps. It must be fed with a #10 conductor from a 30 amp breaker.
90 kW on 480 volts single phase would be 187.5 amps. On 480 v 3-phase it would be 108 amps.
