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

2021-3-1  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

SMB: Closed vs Open circuit? ScubaBoard

2008-9-7  I have used open, closed and semi closed. In my opinion, the latter works best. Open circuit bags can dump at the surface. Closed circuit bags require a QD fitting to inflate - either from a short one on a stage or deco bottle for that purpose or from your wing or drysuit - and while it is not hard, disconnecting things underwater never struck me as smart.
