Basics of Electricity and Electronics #2 | Resistance and equivalent resistances | Electricity 101

This video tutorial from Practical Ninjas covers the basics of resistors, including their role as passive components in electrical circuits. It explains resistance and how it can be calculated using the formula R = ρl/A. The video introduces Ohm's law, which relates current, voltage, and resistance, and demonstrates how to calculate equivalent resistances in series and parallel resistor configurations. The tutorial concludes with a summary and encourages viewers to subscribe for more content.
