A resistor resists the flow of current in a circuit but a transistor changes the amount of current through a device. This is called current magnification. Field effect transistors FETs and MOSFETs (metal oxide semiconductor field effect transistor) may also change the amount of current to a load lastly a variable resistor or a potentiometer or a variable resistor can variate the amount of current at your will

How is resistance used in a space heater?

In an electrical space heater, electrical current dissipates energy into heat, and the heat radiates from the element. In a fuel powered space heater, an orifice throttles the fuel feed (resistance to flow), which controls the heating rate. In a steam powered space heater, an orifice throttles the steam (resistance to flow), which controls the heating rate.


If a heater claims to be 1500 watts how long would it take for that heater to draw 1500 watts?

Watts is the amount of power the heater has and amps would be the draw- if it is a 120 volt heater than the amps would be 12.5 amps and it is instantaneous


Testing the Electric Hot Water Heater Element?

If the water from the faucet is tepid or cold, it might be time to check the electric hot water heater element. Electric hot water heaters are equipped with two heater elements that heat water. They do so through an electrical current the goes through the element. The lower element does the hard work and is most likely to be the first that burns out. Turn off the electricity, and disconnect the wires at the heating element terminals. Set the multimeter to read resistance. Touch the clips on each terminal of the element. If the Ohmmeter doesn't budge, the element is shot.


Is electric heater require oxygen to burn?

No, electric heaters work by running electric current through resistors which produces heat. same as an element on an oven range top.

Why does electric bulb become dim when electric heater in parallel circuit is switched on?

The electric heater draws some of the electrical current in the circuit, which reduces the current available for the electric bulb. This leads to a decrease in the brightness of the bulb as it is receiving less power.

Why does your circuit braker shut off when you turn on your heater?

Your circuit breaker shuts off when you turn on your heater because the heater draws a significant amount of electrical current, potentially exceeding the circuit's capacity. This overload causes the breaker to trip as a safety measure, preventing overheating and potential fire hazards. Additionally, if there are any underlying electrical issues or faulty wiring, this could also contribute to the breaker tripping. It's advisable to consult an electrician to assess the situation.


What item is designed to change electrical energy into heat energy?

An electric heater is designed to change electrical energy into heat energy. It typically consists of a heating element that generates heat when electricity flows through it.
