Resistance is an electrical phenomenon. When you send electricity into a resistor, less goes out the "outlet lead" than went in the "inlet lead." The difference between inlet and outlet is dissipated as heat. If you're building a radio or something, excess heat isn't good. Sometimes you want the heat, so to get as much as you can you use a massive resistor.

What is the working principle of electric iron?
Heat generated by electrical resistance. Thermal mass of a metal plate.
Why the wires leading to an electric iron remains cold while the element gets hot?
This happens because wire have less resistance.
What is the difference between a resistance and a capacitor?
resistance refers to the resistance of flow of electric current wile a capacitor is an electric device that stores energy.
What is the SI unit for an electric resistance?
The unit for resistance is the Ohm.
How is heat energy produced in electric iron?
A resistor placed across the power line: I squared R (current x current x resistance) = heat in watts.
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.
How electric flat iron energy is transformed?
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.
How energy transformed 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.
How energy is transformed in electric flat iron?

Does iron have poor electric current?
Steel & Iron conduct electricity, but have high resistance. They make good heating elements.
What is the difference between electric soldering iron and ordinary soldering iron?
An electric soldering iron is heated by an electric resistance coil inside. Others may be heated either by a gas(like propane) flame, or by sticking them in a forge between uses.
What is the principle of electric iron?
Heat generated by electrical resistance. Thermal mass of a metal plate.
How is electricity used in an electric iron?
Electric iron contains a resistance wire (nichrome) . When a current of I amp is passed through the wire, electrical energy equal to I^2Rt (joules) is produced which is entirely converted to heat. This is a unique characteristic of resistance element as compared to capacitors or inductors where there is no power dissipation. Here R = resistance of the wire in ohms and t= the amount of time that the current passes through the resistance wire. The metal base at the bottom of the electric iron is thus heated up.
What properties are needed for the heating element of an electric iron?
a wire of high resistance and high melting point
What is the working principle of electric iron?
Heat generated by electrical resistance. Thermal mass of a metal plate.
When was the electric iron invention?
When Was The Electric Iron Invented? When Was The Electric Iron Invented?
Why does an electric iron have a resistance of 15 ohms?
I never measured the resistance of an electric iron, but: the 15 ohm resistance is probably required to develop a required 806 watts of power. Using Ohm's law, I(current) = E(voltage)/R(resistance), therefore I(current) =110 volts/15 ohms = 7.33 Amps (current), and, Power (watts) = E(voltage) X I(current); 110 volts X 7.33 amps = 806 watts. The iron requires that wattage to develop enough heat in the sole of the iron. Hope this helps.
