These 5 tutorials introduce and cover Nodal Analysis for circuits, and Supernode Analysis. There is a dedicated video to introduce both Nodal Analysis and Supernode Analysis, and 3 fully worked through example problems with various configurations of nodes, branches, and power sources (current sources and voltage sources). Generally, if you follow the steps laid out in these lessons, you'll be solving these problems like a boss! These tutorials are part of a full Circuit Analysis Course.
Here are 7 tutorials that cover Series and Parallel Resistors. In the lessons, I go over how voltage division and current division work, and a few examples of each. I also run through a more complicated example that involves both voltage division and current division, but you'll see in the end that it's actually pretty straightforward to combine the two when seeking the equivalent resistance of a circuit. The full circuits course can be found here.  Here are 9 new video tutorials that cover Ohm's Law, Kirchhoff's Laws. They introduce the concepts and also go over a few worked examples of varying difficulty.
The rest of the Circuit Analysis course can be found here.  12 free tutorials covering circuits basics are up and ready to go. These tutorials mark the beginning of a full course on circuit analysis that will be located permanently at https://www.engineer4free.com/circuits.
All 12 circuits tutorials can be found below, or in the course page above.  With 52 free tutorials, the Engineering Dynamics (Mechanics) course is now complete. The course covers linear motion, projectile motion, circular motion, kinetics, work & energy, impulse & momentum, and rigid body rotation.
You can find the dynamics lessons here. In addition to the video lessons, I also created an additional 51 fully solved dynamics problems with solutions. These are available to Patreon supporters. If you found the tutorials helpful and want to support my work while getting some extra material, please consider becoming a Patron. You can find the practice problems with solutions here. The final section of Engineering Dynamics is complete. In it you'll find 5 video tutorials and 8 fully solved practice problems. The videos make up numbers 48 - 52 in the Dynamics Course. They are also linked below for convenience 
The additional 8 practice problems can be found here with the rest of the dynamics problems & solutions.  A new section of the Engineering Dynamics course is complete! With 10 video tutorials, and 10 extra solved practice problems, the Impulse & Momentum chapter is ready to go. You can find the new lessons numbered #38-47 in the full dynamics course, but they are also listed below for convenience.
The additional 10 practice problems can be found here with the rest of the dynamics problems & solutions.
