Write the working of electrical bulb, electrical iron, electrical heater
Answers
Explanation:
all the three devices are based on the same principle: when electricity is passed through a coil or conductor of high resistance, a lot of energy goes out as heat and light , which can be used in applications such as the three devices above...
electrical bulb has a complete circuit where the two terminals are connected to the battery and a switch is connected to the connecting wire. The bulb consists of a tungsten wire of a very thin diameter which is a very good conductor of heat and light. when the switch is turned on, the electricity flows through the bulb and because of High resistance of tungsten, it starts to glow at a very high brightness. Similarly, electric iron has a copper coil and the working is same as the bulb.
this device works on the principle of heating effect of electric current
