Posted on December 2, 2014 | By Rick Grigalunas | Leave a response

There are many, many types of resistors that are used for numerous applications. Just what is a resistor? Let me try to explain. A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. Resistors act to reduce current flow, and, at the same time, act to lower voltage levels within […]
