Answer to Question #273850 in Electric Circuits for mickii

Question

The diode is considered shorted when both anode and cathode has?

Answer 1

A diode is considered shorted when both anode and cathode has the same voltage drop reading.

Therefore, a shorted diode behaves as a closed switch allowing current flow through it irrespective of its bias.

A common reason for a shorted diode is usually a large reverse voltage.

A shorted diode can be identified by a metre. If the metre indicates low resistance in both direction,then the diode is said to be shorted.
