Short Circuit

Any damage to a circuit is classified as a short circuit.

There are three types of common failures that can occur in a circuit:

  • Open circuit  - break in the path of current flow
  • Short to ground  - circuit grounded before load
  • Short to power  - circuit path is exposed to another source voltage
