Identifying which diodes are on in a full wave rectifier
Yes, that is correct with regard to which diodes are conducting.
Where the current &quot;enters&quot; and &quot;exits&quot; depends on whether you view current as electron flow (ie. coming from the negative terminal of the current source) or &quot;conventional&quot; current flow (ie. coming from the positive terminal).  That's a matter of habit and local customs.  Your statement is proper for conventional current flow.
