If I use a three phase electric ac and heater is it more economical that using a 3 phase gas ac and heater?
Well, as far as I know, there is no 'gas' A/C. The A/C will be electric, regardless of the type of heat used. Whether electric heat or gas heat would be more economical is really dependent on your electric and gas utility rates and the efficiency of the appliances involved.
How many amps does a 1 phase heater draw if it run on 8kw?
To answer this question the voltage of the heater must be given. I = W/E.
How to build a Rotary phase converter?
A simple Rotary phase converter is just a motor generator set. An electric motor running on the input voltage/current/phase/frequency. it drives a generator that supplies a different voltage/current/phase/frequency. So an electric motor and an electric generator connected together mechanically, either on the same shaft, or via gears, constitutes a Rotary phase converter. the above is incorrect, the motor/generator is the same motor, just one 3 phase motor is needed, it will run on T1 and T2, and put out L1, L2, and L3. You just need to know how to wire it up and what to do to get it to spin over on simple single phase 220, it will create three phase 220.
What is noise filter?
noise filters are used in electronics and electric curcuts to reduce the the noise level which the electric switching generats sometimes the are single phase and there are three phase also the most used noise filters are ssr emc filters
What is the amps for 6000 watts 415 volts 3 phase heater?
There are zero amps in a 6kW 3 phase heater. Amperage is the result of dividing the Watts by the Voltage. A = W/E. Without stating the voltage the heater operates on the amperage can not be calculated.
What would full load amps be on a 480volt 90 kw electric heater be pulling 36 amps per leg?
90 kW on 480 volts single phase would be 187.5 amps. On 480 v 3-phase it would be 108 amps.

To made House use electric heater which element is better?
The best element to use is a 3 phase electric heater that has a guard over the element protecting you from brushing against the hot part and stopping the element from starting a fire if the heater is pushed element down onto the floor
Does a two phase heater need a two phase thermostat?
Most electrical equipment are either designed to work on Single phase (two wires) or Three Phase (three or four wires). Two phase equipment are non existent today. A single phase heater will require a single phase thermostat while a three phase heater will require a three phase thermostat.
When a single phase supply connect to a electric heater short circuit not there why?
The electric heater is basically a resistor, designed to have the right resistance to draw the required current. So a 2 kW heater designed for a 230 v supply is really a resistor of 28.8 ohms, so when it's connected the current is 8 amps and the power is 2 kW.
Do you need a neutral to install 480 volts 3 phase heater?
If the heater is rated as a 3 phase 480 volt heater then a neutral is not needed. If the voltage stated is 277 volts three phase then a neutral is needed.
Can a 240 volt single phase load connect between the high leg and regular phase leg of delta connected three phase system?
yes but voltage will be out a little.This ok for something like a heater which wont care.But for an electric motor starting and overheating maybe a problem.In the US this would be 220v single phase and 208 volts 3 phase.
What phase of mitosis has cells pulling apart?
metaphase
Why do ionic crystals cunduct electric current in the liquid phase or when desolved in water but do not conduct electric current in the solid phase?
Magnetricity.
Can you wire up a 240 volt single phase water heater to 277 volt single phase?
no
Why do ionic crystals conduct electric current in liquid phase or when dissolved in water but do not conduct electric current in the solid phase?
because of the gravity or Magnetricity
Is 380 volts electric motor a single phase or 3 Phase?
It is probably a three phase 50 Hz motor.
