Episode Details

This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams. In this episode you will learn: - How to calculate total resistance for series circuits by summing resistances and for parallel circuits using the reciprocal formula. - The distinct behaviors of voltage and current: current is constant in a series circuit, while voltage is constant across all branches of a parallel circuit. - The effects of open and short circuits, including how an open in a series path stops all current versus only impacting one branch in a parallel path. - How to apply the electrical power formulas (P=IV, P=I²R, P=V²/R) in conjunction with Ohm's Law (V=IR) to solve for unknown values. - A critical OAR exam strategy: qualitatively predict how changes like adding or removing a resistor will affect the overall circuit before performing calculations.
