3. How can we use electrical circuits to build devices?
3.1 How can electrical technology be used to build devices and solve problems?
Electricity and electrical circuits have changed our world. By developing complex circuits that can control motors and machines, we have been able to build robots that can do dangerous jobs and do them much faster than humans ever could. You might find toy robots that are just for fun. You might wonder what robots will look like and what they will be able to do in the future.
