Modern flat irons have thermostats built into them to let a user control the sole plate temperature. More delicate fabrics require little heat while heavy duty fabrics require much more heat. The thermostat is essentially a spring with power contacts on the end mounted on a metal post.
Which part of electric iron is control of heating temperature of iron?
Wired in series with the heating element is a thermostat. The thermostat is made of two electrical contacts that are designed to bend away from each other as the iron gets hot. The knob turns a screw which control how hard the contacts must bend to separate and break the electrical connection.
What are parts of electric flat iron?
Flat irons are constructed with heating elements that become hot when the flat iron is plugged into an electrical source and the power switched on. … There are two plates on a flat iron. The plates are located at each end of the two straight elements that make up the body of the flat iron.
Does a flat iron has an electric motor?
Flat irons are constructed with heating elements that become hot when the flat iron is plugged into an electrical source and the power switched on. Some flat irons are battery powered, in which case they heat up simply by being switched on.
What are the heating effects of electric current?
The heating effect of the electric current is also known as the thermal effect of the electric current. When an electric current tends to flow in the conductor, electrical energy tends to get expended to overcome the frictional resistance between the molecules and the electrons in the wire.
