Electric Bulb : Lighting Effect
Induction Cooker
Answers
Answer:
Due to the collisions of electrons in the wire of resistance, energy is lost causing the heating of resistor.
IDENTIFY THE APPLIANCES WITHOUT HEATING COIL - DEFINITION
Microwave oven and induction cooker are appliances which do not use a heating coil. In a microwave oven, microwaves are used and induction cooker uses eddy currents.
CFL AS A POWER SAVER - DEFINITION
CFL : CFL is the Compact Fluorescent Lamp/Light ,which is designed to save energy and electricity. It has worked as replacement to old incandescent bulbs because it saves 1/8th to 1/5th times of energy and last longer.
An electric bulb is used for light but it also gives heat. This is not desirable. This results in the wastage of electricity. This wastage can be reduced by using fluorescent tube lights in place of the bulbs. Compact fluorescent lamps (CFLs) also reduce wastage and can be fixed in the ordinary bulb holders.
