FE Exam Prep | Current Division Rule Made Easy (Complex Circuit) | Physics & Electrical

How do you find multiple currents in a mixed circuit? In this tutorial, we tackle a comprehensive Physics and Electrical Engineering problem. We start with a 40V source and a network of three resistors (6kohm, 8kohm, and 12kohm to determine both the Total Current IT and a specific Branch Current I1.
​This video is a perfect step-by-step guide for mastering DC Circuit Analysis. We show you how to simplify the parallel branch (8kohm // 12kohm first, find the Equivalent Resistance Req of the entire circuit, and finally apply the Current Division Rule to see how much of the 3.7mA total current flows through I1.
​In this video, you will learn:
​How to calculate parallel equivalent resistance R1= 4.8kohm
​Finding the total circuit resistance Req = 10.8kohm
​Using Ohm's Law to find Total Current IT = 3.7mA
​Applying the Current Division Rule to find branch current I1 = 2.22mA
​Essential Physics principles for series-parallel networks
