This photo is the best for me because it represents the 3 different ways of calculate the Ohm's law. Ohm's law is the relationship between voltage and current in an ideal conductor. This relationship states that voltage across the conductor is proportional to the current. The constant of proportionality is called the resistance, R. Ohm's law is given by V= R×I , where V is the potential difference between two points and V×I is the current flowing through the resistance.
If children are “engineering” their very own original designs, then they are doing the “E” in STEM. It’s the application of their prior knowledge in science, mathematics, and utilization of technology that they apply in order to create! All children are natural “STEMists!” #STEM #science #EngineeringDesignProcess
Multimeters are a vital part of any electronics project, but learning how to use one isn't as simple as it looks. Thankfully, the above video from Adafruit walks you through pretty much everything you need to know.
