Battery outflow current direction
The current I is in the direction of conventional current. Every battery has an associated potential difference: for instance, a 9-volt battery provides a potential difference of around 9 volts. This is the potential difference between the battery terminals when there is no current, and is known as the battery emf, (emf stands for - Download [PDF]
Chapter 18 – DC (Direct Current) Circuits
The current I is in the direction of conventional current. Every battery has an associated potential difference: for instance, a 9-volt battery provides a potential difference of around 9 volts. This is the potential difference between the battery terminals when there is no current, and is known as the battery emf, (emf stands for
Kirchhoff''s Current Law
Here in this simple single junction example, the current I T leaving the junction is the algebraic sum of the two currents, I 1 and I 2 entering the same junction. That is I T = I 1 + I 2.. Note that we could also write this correctly as the algebraic sum of: I T – (I 1 + I 2) = 0. So if I 1 equals 3 amperes and I 2 is equal to 2 amperes, then the total current, I T leaving the junction will ...

19.2: Electric Current
This force is responsible for the flow of charge through the circuit, known as the electric current. A battery stores electrical potential from the chemical reaction. When it is connected to a circuit, that electric potential is converted to kinetic energy as the electrons travel through the circuit. Electric potential is defined as the potential energy per unit charge q). The voltage, or ...

What is the direction of electric current?
The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite direction.
Module 4 Electric Current-The Battery | Science 111
Key Takeaways Key Points. A simple circuit consists of a voltage source and a resistor. Ohm ''s law gives the relationship between current I, voltage V, and resistance R in a simple circuit: I = V/R.; The SI unit for measuring the rate of flow of electric charge is the ampere, which is equal to a charge flowing through some surface at the rate of one coulomb per second.

Kirchhoff''s First Law
We perform analysis on all nodes based on the inflow and outflow of current. Current directions at the node are based on presumed directions of the currents. As long as the assumed directions of the currents are consistent from node to node, the final result of the analysis will reflect the actual current directions in the circuit. Mathematically, Kirchhoff''s …

Reverse battery protection for high side switches
Reverse current paths and directions are shown in red. Also note that the resistor diode ground network does not protect the reverse current in the main FET. This FET current is only limited by the load itself, if the load can not limit the FET current that is electrolytic capacitor load, a blocking diode is necessary as discussed in Section 2.3.
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.

$begingroup$ P.S., A real battery, when operated within certain limits, acts almost like an ideal voltage source in series with a low-value resistor, and when the circuit forces current to flow the "wrong way" through the battery, that will charge the battery. (But note! some batteries are not designed to survive re-charging, and the chemical processes that cause or …
Why do electrons flow in the opposite direction to current?
So you can se, that you have positive direction of travel for electrons, and negative direction of charge, which means, that they are exactly opposite. You could also say, that direction of velocity is negative, and current will than become positive, which will also lead us to opposite direction.

For some electrodes, though not in this example, positive ions, instead of negative ions, complete the circuit by flowing away from the negative terminal. As shown in the figure, the direction of current flow is opposite to the direction of electron flow. The battery continues to discharge until one of the electrodes is used up [3, p. 226].
