Resistors in Series and Parallel

This chapter discusses the resistors in series and parallel. When resistors are connected to each other end-to-end in such a way that they carry the same current, they are said to be connected in series. When resistors are connected to each other such that the same voltage is across each of them, they are said to be in parallel. The chapter also discusses mixed series and parallel circuits. It also presents the application of Kirchhoff's first law and explains how the total resistance of the three resistors of 3, 2, and 6 ohms can be found from the gradient of the graph.
