5 Questions
What are some practical applications of the heating effect of electric current?
The practical applications include electric laundry irons, electric toasters, electric ovens, electric kettles, electric heaters, and electric bulbs.
How does the heating effect of electric current impact the properties of components in electric circuits?
The unavoidable heating can increase the temperature of the components and alter their properties.
What material is commonly used for making filaments in electric bulbs and why?
Tungsten is commonly used due to its high melting point (3380°C), which allows the filament to get very hot and emit light without melting.
Why is it undesirable for electric current to generate heat in many cases?
It is undesirable as it converts useful electrical energy into heat, which is a loss of useful energy.
What is the purpose of thermally isolating the filament in an electric bulb?
The purpose is to allow the filament to retain as much of the heat generated as possible, so that it gets very hot and emits light without melting at such high temperature.
