An OP Amp or Operational Amplifier is a differential input, single ended output amplifier. The gain of these amplifiers is determined by an external feedback element which is usually a resistor network. The symbol for a OP Amp is below: The name “Operational Amplifier” originated from the fact that devices of this design were originally […]

Resistor Basics
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 circuits. RESISTOR TYPES Carbon Composition These are general purpose resistors with excellent transient and surge handling capabilities. The resistance value of this […]
