What are the properties of an open circuit?

An open circuit is defined as a break in the current path, which prevents the flow of current through the circuit. As a result, in an open circuit condition, no current flows at all. This is why the property associated with an open circuit is zero current.

When a circuit is open, there is a discontinuity in the path for current, which means that regardless of the voltage present across the terminals of the circuit, the actual movement of charge carriers (which results in current) does not occur. Therefore, the condition of zero current is the defining property of an open circuit, making it a critical concept in understanding basic electrical principles.
