Why does the chord of an electric heater not glow while the heating element does?
The element is made of special high resistance wire so the power is dissipated in the element rather than the low resistance cord.Power(watts) = Resistance (ohms) X {Current(amperes)}squared
What is the voltage across an electric water heater element that has a resistance of 32 ohms when the current through it is 6.8A?
It is 6 times 8 and the answer is in volts.
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.
Can you turn off hot water heater but still have the breaker turned on Or will it burn the element?
no as it will burn out the element
An electric heater draws a current of 5 amps and its element has resistance of 50 ohms - if it's switched on for 5 minutes calculate the energy in kilo joule?
375 kj
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.
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.
The cord of an electric oven does not glow while the heating element glows.Why?
The cord is manufactured to have as low a resistance as possible, while the heating element is intentionally manufactured with a carefully controlled resistance. The current through the whole loop ... cord plus heater ... is determined by the resistance of the whole loop. The magnitude of the current 'I' is (E/R) ... E = the utility line voltage, R = resistance of the cord+heater. But the power dissipated by each individual resistance in the loop is proportional to the resistance of that section. P = I2R. So the heating element dissipates more power than the low-resistance line-cord does.
Why wont the seat heaters stay on in 2005 Chevy silverado?
you need to check the resistance of the seat heater elment. each seat has an upper and lower element. your probably going to find an open heater element ckt. gm master tech
Which element are used as an electric heater filament?
Nichrome wire is commonly used for resistance wire for heater elements and it is a non-magnetic alloy of two elements nickel and chromium. It has high resistance and resists oxidation. The electrical resistivity is about 65 times that of copper.
Why thermistor is used in gas sensor TGS 2611?
It doesn't, allthough the resistive value is dependant on heater temperature the resistance of the sensor changes due to the presence of certain gasses (methane in this case) while the heater element itself facilitates a catalystic reaction in the sensor element. The temperature of the heating element is self-regulated and dependant on heater voltage.

What is the difference between a filament of a bulb and an element of an electric heater?
The heater element is thicker wire, and has lower resistance. It still has enough resistance to glow red hot (producing heat) but does not glow white-hot and very brightly like a light bulb filament. Also, it lasts almost indeifnitely. whereas the light bulb filament has a finite life - it will "burn out" sooner or later.
Examples of electrical resistance?
Good examples of electrical resistance would be an electrical baseboard heater, electric hot water tank and an electrical kettle. All of these devices use a resistive element to create heat.
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.
