An electric heater is a resistor. It is a resistor with the right amount of resistance to take the required amount of power at the specified voltage. With a case to put it in and louvres to let the warm air circulate, that is a heater.
Resistance in ohms is equal to the voltage-squared and divided by the watts.

How a electric heater works 2 references?
An electric heater is a resistor that dissipates electric power when a voltage is connected across it and a current flows through it. The amount of power in watts is equal to the voltage times the current in amps. Typical space heaters for use in the home are 1.5 kW to 3 kW to heat a single room.
What are the features of an efficient electric heater?
The main feature of an efficient electric heater is, that is used up to 30% less engery than a conventional electric heater. This reduces the cost of the heater.
Electric heater A has a power rating of 1kw. Electric heater B has a power rating of 800W. which transfers the most energy in 2 hours?
Electric rating of 1Kw
Is electric water heater best to use with oil boiler?
Domestic coil in boiler better than electric water heater.
What happens when a electric heater is switched on?
The heater element is a coiled wire resistor that draws enough current to supply the intended amount of power, which might be 1.5 - 3 kW. Quickly the temperature of the wire rises until it reaches an equlibrium where the heat power conducted away by convection is the same as that draw from the power supply.
What is stepped resistor?
The resistance that controls a heater motor in the electric system .
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.

Why does the cord of an electric heater not glow while the heating element does?
The heating element of an electric heater is a "resistor", the cord which conducts the electricity is not. The resistance of the element of an electric heater is very high. As current flows through the heating element, it becomes red hot and glows. On the other hand, the resistance of the cord is low. It does not become red hot when current flows through it.
