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.
Current | Physics
Note that the direction of current flow in Figure 2 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.

How to find current direction inside battery?
The battery with the smaller emf will have current going out of its negative terminal and into its positive terminal and if it was a rechargeable battery it would be recharging with electrical energy from …
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 …
9.1 Electrical Current
Current in a Circuit In the previous paragraphs, we defined the current as the charge that flows through a cross-sectional area per unit time. In order for charge to flow through an appliance, such as the headlight shown in Figure 9.5, there must be a complete path (or circuit) from the positive terminal to the negative terminal. ...
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.
Battery Internal Resistance: A Comprehensive Guide
Battery Selection: For applications requiring high current bursts, like digital cameras or drones, batteries with low internal resistance are essential. Battery Health : A rising internal resistance can be an early warning sign of a failing battery.
Physics Tutorial: Electric Current
If the two requirements of an electric circuit are met, then charge will flow through the external circuit. It is said that there is a current - a flow of charge. Using the word current in this context is to simply use it to say that something is happening in the wires - charge is moving. Yet current is a physical quantity that can be measured and expressed …
What is meant by alternating current "reversing direction"
When we say that an alternating current reverses its direction, we mean that, every 16.7ms (for 60Hz system), it changes its direction in that loop, from clockwise to counterclockwise and back. At a given moment, if the current flows toward your house in one of the two wires, it flows away from your house in the other wire.

Alternating Current (AC) vs. Direct Current (DC)
Both AC and DC describe types of current flow in a circuit. In direct current (DC), the electric charge (current) only flows in one direction. Electric charge in alternating current (AC), on the other hand, changes direction periodically. The voltage in AC circuits also periodically reverses because the current changes direction.

What happens if I change the polarity of the battery?
When the capacitor is first charged, it has received $frac{1}{2}C(+V)^2$ joules of energy from the battery.. By reversing the battery, you create a potential difference which causes current to flow in the opposite direction, which will at first discharge the capacitor, until the voltage across it returns to zero. At that point the capacitor stores no …
2.1.2: Conventional Current Flow and Electron Flow
Why do we define the direction of current as the positive charge flow direction? Benjamin Franklin (pictured in Figure 2.1.2.1 ) began experimenting with the phenomenon of electricity in 1746. In 1752 he performed his famous kite experiment proving that lightning is a form of electricity by capturing charge from storm clouds in a leyden jar (an early form of an …
