Current Electricity

A battery, a wire and a bulb. A few rules tell you what every part of a circuit does. In this chapter you learn how current, voltage and resistance fit together. You join resistors one after another (in series) and side by side (in parallel). You also solve circuits that have more than one battery. Python checks your work.

Electric Circuits

Why does a bulb get dimmer when you add a second bulb in series? Why do the lights in your house stay bright when you switch on a fan? In this course we learn how current, voltage and resistance fit together. We start with Ohm's law and resistors in series and in parallel. Then we use Kirchhoff's two rules to solve circuits with more than one battery, and we let Python check our work. It is a solid base for Class 11 and 12 exams, and for JEE and NEET circuit questions.
