 **Figure.** **[Current](https://en.wikipedia.org/wiki/Electric_current)** is the flow of charged particles—in this case, electrons—through a conductor. In the animation above, we are illustrating "electron flow" as a dotted green line, which flows from the negative terminal of the 9V battery, through an LED and resistor, and then back to the 9V battery to its positive terminal. Note that this is actually opposite from *conventional current* flow, but we'll get to that below. Animation from [The Engineering Mindset](https://youtu.be/kcL2_D33k3o).

 This is similar to current in a circuit—atoms are tightly packed in a material with orbiting electrons. When a voltage is applied, these electrons start to "hop" from one atom to another through a conductor but do not instantly travel from A to B (see [video](https://youtu.be/OGa_b26eK2c?t=472)).

 **Figure.** This animation shows how a resistor can be placed between two wires to reduce current flow. Notice how electrons flow freely through the copper wire. With the resistor, these electrons "collide" with other atoms and themselves, which restricts electron flow (and also transforms some energy as heat).

 **Figure.** This animation shows how a resistor can be placed between two wires to reduce current flow. Notice how electrons flow freely through the copper wire. With the resistor, these electrons "collide" with other atoms and themselves, which transforms the electrical energy to thermal energy and induces a voltage drop.
