A resistance heater is a type of heating device that generates heat through the process of electrical resistance. When an electric current passes through a resistive material, it encounters resistance, which converts electrical energy into thermal energy. These heaters are commonly used in various applications, including industrial processes, space heating, and household appliances like toasters and electric stoves. They are known for their efficiency and simplicity in design.

What is the voltage of a small electric heater if the heater is drawing 12 amperes and has a resistance of 10 ohms?
Voltage is current times resistance, 1.2 x 110 = 132 volts.
Does the resistance of heater coil remains same when current flows through it?
Typically resistance rises with temperature.
What does high or low voltage do to the capacity of an electric heater?
Yes, voltage effects the output of electric heaters. The wattage output rating of the heater will not be reached due to the lower applied voltage. For example if the heater is 5000 watts at 277 volts, the current is I = W/E 5000/277 = 18 amps. The resistance of the heater is R = W/I (squared) = 5000/18 x 18 (324) = 15.43 ohms. Applying 220 volts on the same heater whose resistance is 15.43 ohms results in this new heater wattage rating. W = E (squared)/R = 220 x 220 (48400)/15.43 = 3137 watts. W = watts, I = amperage, R = resistance in ohms and E = voltage.
How do you calculate the resistance of a heater element that's uses 220v and draws 11amps?
The equation you are looking for is R = E/I.
In a home that has 120 v service heating is provided by electric resistance heat with an overall resistance of 40 ohms hom much heating power will the electric resistance heater generate?
The formula you are looking for is W = E(squared)/R, W = Voltage (squared) divided by Resistance.
Does an electric motor have different resistance than an electric heater?
Yes it would be unlikely an electric motor coincidentally exactly matched the resistance of an electric heater.
Where is the heater resistor on a 2003 Chevy Cavalier?
There are heater-resistance wires in the glass of the back windshield.
What is the voltage of a small electric heater if the heater is drawing 12 amperes and has a resistance of 10 ohms?
Voltage is current times resistance, 1.2 x 110 = 132 volts.
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.
Does the resistance of heater coil remains same when current flows through it?
Typically resistance rises with temperature.
Does resistance of heater coil remains same when current flows through it?
Typically resistance rises with temperature.
Which has a more resistance a 100 W bulb or a1000 W heater?
A 1000 W heater would have more resistance compared to a 100 W bulb. The higher the power rating of an electrical device, the lower its resistance, as resistance is inversely proportional to power. So, the 1000 W heater would have lower resistance than the 100 W bulb.
What is stepped resistor?
The resistance that controls a heater motor in the electric system .
An electric heater is stretched to increase its length by 25 percent what is the increase in resistance?
The resistance of the electric heater will increase by approximately 56.25% (25% increase in length results in a 56.25% increase in resistance). This relationship is given by the formula: new resistance = (1 + 0.25)^2.
2004 e320 Mercedes Benz why is your heater bowing cold air?
check the heater control valve it should be 10 ohms of resistance
How much current will an electric heater draw from a 110-volt line if the resistance of the heater when hot is 26.7 ohm?
4.12A. V=IR
Why is heater blower on citroen dispatch intermitent?
Check the back of the heater switch. The electrical plug may be having an melt down from resistance.
