ABSTRACT
This chapter provides an overview of a series circuit, a parallel circuit, and a series-parallel circuit. It explains the Kirchhoff's voltage law and current law. The chapter explores the potential hazard of an open circuit in a series circuit. It helps readers to calculate the total resistance of a series resistive circuit, a parallel resistive circuit and series-parallel resistive circuit and the current flow through a series resistive circuit. For current to flow through individual circuit components, such as resistances, there must be a difference in potential across each of those components. Voltage dividers are widely-used in electronics' circuits, where a single direct current voltage source is often required to provide lower voltages to various load circuits fed from the same supply. The chapter also helps readers to calculate the voltage drop appearing across each resistor in a series resistive circuit, a parallel resistive circuit, and series-parallel resistive circuit.
