| Feb 4, 2022 at 9:39 | comment | added | Stdugnd4ikbd | @M.Enns current by definition is amount of electrons that pass through area of conductor per time. Increasing currency can mean only two things: there came more electrons to the wire (from nowhere), electrons are started to move faster. Hence, higher current, higher net speed | |

| Feb 3, 2022 at 17:20 | comment | added | Kyle B | I would caution about imagining the motion of electrons to visualize what's going on in a circuit. The magic is actually in the electromagnetic fields surrounding the wires. Just like waves on a pond can have different amplitudes and speeds, but the water molecules themselves barely move. | |
| Feb 3, 2022 at 17:17 | comment | added | Kyle B | Well all else being equal, you're actually right about current decreasing with increasing frequency. But not really because of the concepts you put forth (which i find a bit confusing TBH). All wires have a self inductance....it doesn't need to be wrapped in a coil shape to be an inductor...and an inductor has an increasing impedance as a function of frequency. By ohms law, impedance goes up, voltage is constant, then current must go down. | |
| Feb 3, 2022 at 16:38 | comment | added | DKNguyen | "will the current (amplitude speed of electrons) decrease with high ac voltage applied?" Is this a typo? Because you say current decreases with increasing voltage here. Also, I don't think amplitude or speed is the definition of current. | |
| Feb 3, 2022 at 16:22 | comment | added | M. Enns | Can you briefly describe how Ohm's law can be used to calculate the maximum speed of electrons in a conductor? | |
