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 meant by the resistance of an electrical component?
Think of it like this: Friction causes you difficulty in pulling heavy objects on a carpet. This frictional force is similar to electrical resistance. It is one of two ways to define how easily electricity will travel through an electrical element.
Is every resistance load resistance?
No. Load resistance is the value of the element actually doing the work of the circuit it is connected to. A speaker connected to an amplifier is the load.
How do you draw a circuit diagram of an electric blanket?
The way I have done this with things such as heaters, window defrosters, etc. is to model the heating element as a resistor (or a set of resistors in different parallel and series combinations, based on the layout). The wire used in the electric blanket (the heating elements) should have a specific resistance per length; calculate the length of the different sections, and create a lumped resistive element of this total length.
What is the resistance of the heating element of an electric iron it the ampere draw is 8 amperes when 115 volts are applied?
Using Ohm's Law (E = I R) Voltage = Current x Resistance or switch around to get R = E / I: 115 volts / 8 Amperes = 14.375 Ohms The above is correct for DC current but is close enough to be used for AC current.

How the electric transform in electric flat iron?
An electric iron has a heating element that offers electrical resistance. The resistance causes friction to occur in the electrons and causes a heating effect.
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.
What would affect the brightness of a lamp?
Voltage applied (voltage at source, resistance of wire and conections etc), ground resistance, designed brightness of element in comparison to the applied voltage
How electric flat iron energy is transformed?

Does the wire in the electrical cord of an electric have a higher or lower resistance than the Heating element inside the kettle?
The wire in the cord has much lower resistance than the heating element. The heating element is a resistive or resistance heating element. Resistance in the quality of a substance or material that causes it to limit current flow, and it get heated up in the process. The heating element has all but the smallest fraction of the resistance in the circuit, so the heat, that thermal energy that get the water hot, is generated by the resistance of the heating element.
