Electric Current and Current Flow
Definition of current. Electric current is normally referred to as the flow of charges through a conductor. It can be defined as the amount of charge that flows past a cross-section area in a conductor. In other words, the term "current" can be defined as the rate of flow of charges through a conductor.

20.1 Current
Note that the direction of current flow in Figure 20.3 is from positive to negative. The direction of conventional current is the direction that positive charge would flow. Depending on the situation, positive charges, negative charges, or both may move. In metal wires, for example, current is carried by electrons—that is, negative charges move.
Which is better for monitoring a vehicle''s electrical system
Short answer: A voltmeter, by far. Electrical guru Mark Hamilton of M.A.D. Enterprises points out that amperage is a measure of current flow, so an ammeter is actually a "flow meter" that''s intended to measure current flow to the battery (under normal conditions) or discharge from the battery (in the case of alternator system failure).
