What is an Open Circuit?
Open Circuit Definition
An open circuit is defined as a state in an electrical system where no current flows due to a break in the circuit, maintaining a non-zero voltage across its terminals.
Open-circuit characteristic
The current flowing through the circuit is zero, and voltage is present (non-zero).Pwer is also equal to zero, and no power dissipates from an open circuit.The open circuit resistance is infinite
The difference between closed circuit, open circuit and short circuit is shown in the figure below
