Current direction inside a conventional battery
The method is basically curling the four fingers in the direction of the current with the thumb pointing against the direction of incoming B-field. But my method is actually 1. Outstretching the four fingers in the direction of B-field (the trick is to do this at a place where the B-field lines are perpendicular to the segment of the loop) 2. - Download [PDF]

Direction of current flow in a circuit
In such a case, with the capacitor now discharging, donating energy, that current must be in the direction in which it exits via the capacitor''s higher potential terminal, just like a battery. Note: Actually, it is possible for a resistor to donate energy to other parts of a circuit, in the form of noise current.

1. Conventional Current
The direction of current that you are familiar with is known as conventional current and is the direction that positively charged particles would flow in.

Electric potential and the flow of electrons in a battery
The electrons are confusing and you should ignore them. Conventional current flows from positive voltage to negative voltage.. Electrons are negatively charged and attracted to positive objects: they will flow "up" an electric field towards the positive voltage.. The reason you should ignore the electrons is not only are they going the wrong way, but not all …

As such, an early convention for the direction of an electric current was established to be in the direction that positive charges would move. The convention has stuck and is still used today. 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 ...
Conventional current is the direction of electric current from the ...
Hint: Recall that the flow of electric current in a circuit is caused by the flow of electrons from the anode to the cathode of a battery. Also, electric current defines the direction of flow of positive charges in a circuit. Use this to arrive at the appropriate direction of flow of conventional current given that charge carriers always flow from a region of high concentration to a region of ...

The direction of the current inside the battery is the same as outside the battery. In other words, the current is moving in the same direction everywhere in the loop. Conceptually, an …
Electric potential and the flow of electrons in a battery
Conventional current flows from positive voltage to negative voltage. Electrons are negatively charged and attracted to positive objects: they will flow "up" an electric field towards the positive voltage.
Electric current
The conventional direction of current, also known as conventional current, [10] [11] is arbitrarily defined as the direction in which positive charges flow. In a conductive material, the moving charged particles that constitute the electric current are called charge carriers. ... the flow of ions inside a battery, ...

Current Flow in a Battery: Does It Really Go from Positive to …
Current flow in a battery happens through the movement of electrons. Electrons move from the negative terminal to the positive terminal. This movement creates …
Confused on direction of current through capacitors.
$begingroup$ If you measure with a voltmeter on the two terminals of the capacitor, the negative terminal is the one receiving electrons from the source. BUT a second voltmeter measuring from the negative terminal of the voltage source to the negative terminal of the capacitor would show that it is more positive than the source terminal until the capacitor …

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.
