Current Dividers Explained!

This physics video tutorial provides a basic introduction into the current divider circuit. It explains how to calculate the current flowing through each resistor in a two-resistor parallel circuit using a simple formula given the total current entering the circuit. It also includes examples with a parallel circuit with three resistors and one with four resistors in parallel. The voltage across each resistor in a parallel circuit is the same and the currents flowing through each branch must add to the current entering the circuit based on Kirchoff’s current law / junction rule. This video contains plenty of examples and practice problems for you to master this concept.
