Battery details the current is negative
The smartshunt always is showing a negative current. It doesn''t matter what state the charge controller is in (bulk, absorption or float). My gut tells me that something is not right and that I should see a positive current going into the battery bank at least during the bulk or absorption phase. Any help would be appreciated.

Now back to our battery. The positive and negative electrodes are separated by the chemical electrolyte. It can be a liquid, but in an ordinary battery it is more likely to be a dry powder. ... The higher the voltage, the more …
Does the Current Flow Backwards Inside a Battery?
The Basics. A battery is made up of an anode, cathode, separator, electrolyte, and two current collectors (positive and negative). The anode and cathode store the lithium. The electrolyte carries positively charged lithium ions from the …
Why does current travel away from the battery''s negative terminal …
Current flows from higher to lower potential in the external circuit not through the battery. So the current flows from the larger bracket as you call it, anticlockwise, then to the smaller bracket. A good way to remember this is to note that in the symbol for DC source, there is no internal line connecting the brackets, so if there is any current flow, it is from one bracket to another via ...
Confusion between positive and negative terminals of a battery
Outside a battery, current flows from its positive terminal to its negative terminal. Inside the battery, to stop charge building up, the current must flow the rest of the way round, from the negative terminal to the positive terminal. This flow is driven by the chemical reactions in the battery. In an electrolysis cell the current flows ...
Why am I getting negative current on the right loop of the …
$begingroup$ @rob The schematic in the question clearly shows that the voltage source on the right is negative. Having that in mind, please point one of the number of logical and arithmetic errors.As for the complete answer to a homework-like question, I do not feel that way.The only thing I changed in OP''s proposed solution is the voltage source sign, and …
What is the direction of the electricity flow in a DC circuit?
$begingroup$ There is a convention for the technical direction of the current: positive current flows from the plus pole of a battery to the minus pole by convention. The microscopic details of conduction in a specific medium/conductor are a different thing. In some conductors, like metals, it is actually electrons that flow.
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.
Battery Circuit Diagram: Understanding the Positive and Negative …
The battery circuit diagram represents the arrangement of the battery, its positive and negative terminals, and the wires that connect it to other components in an electrical circuit. Positive and negative terminals: The battery circuit diagram typically includes symbols to represent the positive and negative terminals of a battery. The ...
Electric Current
Electric current is defined as the rate of flow of electrons in a conductor. The SI Unit of electric current is the Ampere. Login. Study Materials. ... Henceforth, the current flowing in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery.
19.1 Ohm''s law
However, because a positive current moving to the right is the same as a negative current of equal magnitude moving to the left, as shown in Figure 19.4, we define conventional current to flow in the direction that a positive charge would flow if it could move. Thus, unless otherwise specified, an electric current is assumed to be composed of ...
17.5: Batteries and Fuel Cells

How Do Batteries Work? | OpenLearn
To kickstart the chemical reactions in the battery, you just connect a wire between its negative and positive terminals, and a steady stream of electrons (a current) is produced as the reactions get under way. If an …
Which Way Does Electricity Flow?
It was discovered that if a battery, with its positive side connected to the added electrode (plate), and its negative side connected to the filament (cathode), an electrical current would flow. If …
Lead–acid battery
The lead–acid battery is a type of rechargeable battery first invented in 1859 by French physicist Gaston Planté is the first type of rechargeable battery ever created. Compared to modern rechargeable batteries, lead–acid batteries have relatively low energy density spite this, they are able to supply high surge currents.These features, along with their low cost, make them …
19.2: Electric Current
Voltage is the energy per unit charge. Thus a motorcycle battery and a car battery can both have the same voltage (more precisely, the same potential difference between battery terminals), yet one stores much more energy than the other. The car battery can move more charge than the motorcycle battery, although both are 12V batteries.
