Can you run a 2 kw convector heater through a 25 amp trip switch at 240 volts?

Yes, the total amperage load of a 2000 watt heater at 240 volts is 8.3 amps. Keep in mind that the wire feeding the heater must be a #10 because the breaker is rated at 25 amps. A wire's ampacity rating can be larger that the breaker amperage rating but never smaller. Example, a #14 rated at 15 amps or a #12 rated at 20 amps can not be connected to a 25 amp breaker. The 25 amp breaker does not trip until it reaches 25 amps well over the allowable amperage of the #14 amd #12 wire. This is why a #10 wire must be used as its rating is 30 amps.

If the current through a heater coil is 5 amp and the supply voltage is 120 volts the coil resistance is?
The formula you are looking for is R = E/I. Resistance = Volts/Amps.
How does an electric switch heater work?
The electric switch heater uses high voltage, from 480 to 750 volts, through coils that are fixed both on the web of the rails and with "crib heaters" that are laid underneath the movable rods between the ties. These are typically more effective than other types of switch heaters because of the ability to provide the crib heaters, which cannot be used with gas heaters. The heating elements are provided throughout the area of the movable parts of the switch layout.
Can i run a 240 volt water heater on 120 volt?
No. A water heater requires a 240 volt connection and cannot be re-wired to run on 120 volts. There isn't enough amperage in 120 volts to power the heating rods that are inside.
Feed drops to zero volts when light switch is turned on back to 120 volts when turned off feeds fluorescent lights?
voltage is measured by voltagd drops. When a switch is open/ off there is a voltage difference between one side to the other. when the switch is on there is no drop from one side of the switch to the other. That is normal operation. If switch is on, and you get a voltage reading across the switch, the switch is bad.
If a 325 watt heater has a current of 6.0A what is the resistance?
Watts = Current x Volts with your resistive heat application. To figure out resistance you need to know voltage and current. Since you are drawing 6 amps then Volts = 325/6. This means that there is about 54 volts supplying the heater which seems like a very strange supply voltage. Since Volts = Current x Resistance the resistance = 325/36.
Can 400volts heater element get supply from 230 volts?
Yes you can run a 400 volt heater on 230 volts but you will not get the full wattage rating that the heater produces at 400 volts.
How do you calculate the current flowing through a heater?
The formula you are looking for is I = W/E. Amps = Watts/Volts.
What is the current through the 150 ohm heater?
At 110 volts it is 0.8 amps. At 220 it is 0.4 amps. I=E/R. I=amps.E=volts R=resistance.
If the current through a heater coil is 5 amp and the supply voltage is 120 volts the coil resistance is?
The formula you are looking for is R = E/I. Resistance = Volts/Amps.
What state is the switch when you have 0 volts on one side and 120 volts on the other?
The switch is in the OFF position.
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.

Why does the electricity not cross over the switch when it is open?
The voltage potential is not high enough through design of the switch when it is open. That is why switches and receptacles have voltage ratings. Put a potential of 10000 volts across an open switch and you will have a piece of charcoal.
How many amps does a block heater draw?
To answer this question the wattage of the block heater must be stated. Amps = Watts/Volts.
If an electric heater has a red blue and green wire that has been cut off how do i know if its 120 volts or 240 volts?
A label.
Why does ceiling light still have 50 volts going through neutral and hot wires when switch is off?
Because the switch has a fault and needs replacing before you waste a whole lot of energy (which you pay for).
