Current and Resistance

This course dives into the fascinating world of electrical resistance, a core concept in understanding and designing circuits. You’ll start by exploring what resistance is and how it’s connected to the resistivity of materials. We’ll look at how factors like material properties, size, and temperature influence resistance, and delve into the microscopic details of how electrons interact with atoms.

Next, we’ll see how resistors work in real-world scenarios, learning about their roles in series and parallel circuits. Ohm’s Law will become a handy tool as we break down voltage, current, and resistance in practical applications. For those ready to go deeper, we’ll tackle advanced topics like how resistivity changes with temperature and how resistors are designed for specific needs.
