Open Circuit: What is it? (And How Does it Differ To a ...

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 disconnected.

Closed-circuit systems. The efficiency of the early stages of grinding in a ball mill is much greater than that for formation of ultra-fine particles, so ball mills operate most efficiently by making a coarse product, the fine fractions of this then being separated, and the coarse part being returned to the mill inlet.
