DC and Ohm’s Law

Understanding and using electronics will involve mathematics. It is completely
unavoidable. Math and electronics are intertwined, as are all of the sciences:
physics, chemistry, biology, astronomy. Its what the sciences are: understanding
and describing and predicting the natural processes and phenomonen with
mathematics. If you are interested in electronics, you will have to obtain some
level of expertise in math. To begin with, our friend Ohm’s Law and relatively
simple algebra will get you started. Using algebra will allow you to comprehend
and understand the behavior of DC electricity and eventually AC, radio,
electrooptics, microwave, cell phones, and television. Let’s get started.
