If the heater is RATED at 5kw and is DESIGNED for 240v, it will draw 20.8 amps if 240v is applied.
I say it this way because you probably will not have exactly 240v. You may have as little as 220v or as much as 250v and still successfully operate this heater. But the difference in voltages would give you different currents.
For USA, Canada and countries running a 60 Hz supply service...
In general practice you would connect this heater to a 30amp 2-pole breaker using #10 gauge wire.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

How much resistance should be on a 5.0 kw heat strip?
Depends on the voltage. Wattage is Volts x Amps. Resistance (ohms) is Volts divided by Amps. So on a 120V circuit, it would draw 41.66 amps. To do that, it would need a resistance of 2.88 ohms. But on a 240V circuit, it would draw 20.83 amps. That would require a resistance of 11.52 ohms. Determine the circuit voltage, then use that to figure the amps, then use that result to calculate the resistance necessary.
What gauge wire you would use to wire a 5kw heater hvac?
At 120 Volts you would draw about 42 amps. At 240 Volts it would be about 21 amps. For 120 Volts you would need 6 AWG and for 240 Volts you would need 10 AWG.
What would be the amperage draw of a single phase 1200 watt heater if voltage is 120?
10 Amps. Amps=Watts/Volts
How many amps does a router use?
That depends on your router. The current draw of a router (or any other electrical device) can be calculated by: Amps * Volts = Watts If you know any two, you can calculate the third. If (for example) the router draws 750 Watts, and you know that it plugs into 120 Volts, then you can plug into the formula Amps *120 Volts = 750 Wats OR Amps = 750 Watts/120 Volts OR Amps = 6.25 If you would like the answer in volts it would then be about: 120
5000 watts at 240 volt will draw how many amps?
To find amps if watts and volts are known, use the formula; watts / volts = amps or 5000 / 240 = 20.83 amps
How many amps drawn a 110KW motor?
Watts = Volts times Amps. Therefore, if the voltage was 220 volts, the motor would draw 500 amps. If the voltage was 4,000 volts, the motor would draw 27.5 amps. The voltages for large powerful motors tend to be relatively high, for example in the 380 Volts to 11,500 Volts range.

What gauge wire would you need to handle 14 amps at 120 volts?
You would need to use a #12 copper conductor to continuously draw 14 amps at 120 volts.

How many amps would a 2.2kw kettle draw at 240 volts?
A2.2 kW kettle will draw 9.16 amps at 240 volts. I = W/E. Amps = Watts/Volts.
How many amps does a 2000 watt heater draw at 240 volts on each line?
For a single phase circuit, the equation you are looking for is I = W/E. Amps = Watts/Volts.
How many amps does 30KW strip heater draw at 208 volts 3PH?
Assuming it is a 208-volt line voltage (as normal in 3-phase) the phase voltage is that divided by sqrt(3), or 120 volts. Each phase has to supply 10 kW so the current on each phase is 83.3 amps.
How many amps does a 2x4' lay-in fixture draw at 277 volts?
Check the current draw that is on the label of the ballast.
How many amps does a block heater draw?
To answer this question the wattage of the block heater must be stated. Amps = Watts/Volts.
