how many knows about an iron box ,learn learn it as simple
INVENTOR----Henry W. seeley
INVENTED IN---1882
PRINCIPLE--The principle of the electric iron is that when current is passed through a coil, the coil gets red hot and transfers the heat to the base plate of the electric iron through conduction.this is a common principle for electric fire electric iron and electric water heater
its a conventional iron box used in olden days even now STEAM IRON

- converts electrical energy to heat energy
- it is based on the heating effect of the current
- when a current is passed through a piece of wire, the wire(heating coil/resistor) heats up and emits heat radiation.
- HEATING COIL is nothing but an resistor
- POWER =I^2 R t
- where I is the current passing through the resistor
- R resistor
- t time
"we have seen that iron box consists of a metal plate when current passes through this resistor it gets heated up and hence the metal plate too"
NON ELECTRIC IRON BOX
its a conventional iron box used in olden days even now STEAM IRON
TYPES OF IRON BOX
- AUTOMATIC
- NON AUTOMATIC
- STEAM IRON
