Unit 2: How a microwave oven works?
900 possible mastery points
How do microwave ovens work? To explore this, we need to put together a few pieces, what electric dipoles are, how they behave in the presence of electric fields. But, let's get our basics right. In this lesson, we discuss the flow of the unit!
Where does everything electric start? Electric charge! Let's see what they are, and what rules they obey!
A balloon rubbed with hair, sticks to walls. Why? Learning about charge transfer through friction and induction can help us answer this question!
Although a ball is pulled down by the mighty force of the entire Earth, I can easily counter it with my fingers. Why? How? Mindblown? Let's learn how to calculate electric force & compare it with gravity!
Let's dig a little deeper now, how do charges attract each other from a distance. How do they know what's going on?
In this final lesson, we see how the electric fields in the microwave oven heat up food! It turns out we need to understand the concept of electric dipoles to fully grasp the picture, so we start with dipoles!
