Transistor Switches

  • David Cook

Abstract

When a chip pin provides current like the positive terminal of a battery, it is said to “source” current. When a chip pin receives current like the negative terminal of a battery, it is said to “sink” current. These terms are reminiscent of the water analogy, where water comes out of the source and then goes into the sink.
