“How can we make an electrical switch in our circuit?”


Switches are very useful in circuit elements. With them, we can turn parts of a  circuit on and off. But sometimes we can’t mechanically activate them. So how can we use our engineering mindset to solve this problem? Well, what if we were to use an electromagnet that could actuate upon a switch based upon the current applied? Well, this is the fundamental idea behind electrical relays and are used in circuits applications worldwide.
