Open Circuit: What is it? (And How Does it Differ To a Short Circuit …
What is an Open Circuit? An open circuit is defined as an electric circuit in which current does not flow. Current can only flow in a circuit if it finds a continuous path—known as a "closed circuit". If there's a break anywhere in the circuit, you have an open circuit, and current can not flow. In an open circuit, the two terminals are ...
