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.

How is heat energy produced in electric iron?
Heat energy is produced in an electric iron through the process of electrical resistance. When electricity flows through the heating element of the iron, the resistance of the element converts the electrical energy into heat energy. This heat is then transferred to the baseplate of the iron where it can be used for ironing clothes.
Why the wires leading to an electric iron remains cold while the element gets hot?
The wires leading to an electric iron remain cold because they are made of materials that have low resistance to the flow of electricity, causing minimal heat to be generated. In contrast, the heating element inside the iron is specifically designed to have high resistance, causing it to heat up when electricity flows through it. This allows the iron to reach high temperatures for efficient operation while keeping the connecting wires cool.
What is the working principle of electric iron?
Oh, dude, it's like this: the working principle of an electric iron involves electricity flowing through a coil inside the iron, which heats up due to resistance. This heat is then transferred to the soleplate of the iron, allowing you to smooth out those wrinkly clothes. So, yeah, it's basically just using electricity to make things less wrinkly.
Do toasters work because of the heating effect of an electric current?
Yes. resistance in wires within the toaster causes those wires to become very hot.
What energy changes take place in a electrical iron?
In an electric iron, electrical energy is converted into heat energy due to the resistance in the iron's heating element when the iron is turned on. The heat energy is transferred to the iron's soleplate, allowing it to generate steam or smooth out wrinkles in clothes.
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.
What properties are needed for the heating element of an electric iron?
The heating element of an electric iron needs to have high electrical resistance, good heat conductivity, and resistance to oxidation. Additionally, it should be durable and able to reach and maintain high temperatures to effectively iron clothes.
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.
How is heat energy produced in electric iron?

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.
