7 Difference between Open Circuit and Closed Circuit | Example
Open Circuit: In an electric open circuit, no electrical connection occurs in between the source and load. If any sides of the source or other components disconnect in an electric circuit, the current will not flow. That's why the load will not be activated. Closed Circuit: In closed circuit, closed loop path occurs with the connected source ...
