How To Solve Any Resistors In Series and Parallel Combination Circuit Problems in Physics

This physics video tutorial explains how to solve any resistors in series and parallel combination circuit problems. The first thing you need to do is calculate the equivalent resistance of the circuit which you can use to calculate the current flowing from the battery based on ohm's law. Using the current and the voltage drops across each resistor, you can calculate the electric potential at every point in the circuit which will allow you to calculate the current flowing through any resistor. This technique is useful if there's not multiple batteries in different loops of the equation. Keep in mind, the current flowing in two resistors that are in series with each other is the same. The voltage is the same across resistors connected in parallel. This video contains plenty of examples and practice problems including a current division formula for resistors connected in parallel.
