batteries
$begingroup$ Assuming an external current flow through a battery (which is likely in a circuit with several resistive loads and several batteries, as I saw in mesh analysis problems), it is unclear how the battery''s electrolyte can serve a dual conductive function for both battery''s internal charges and an external circuit''s electron current
Can current flow in two different directions at the same time?
