Slow decrease and increase of supply voltage
Webb4 nov. 2024 · The allowable current for a given size wire is determined by the how much temperature rise is acceptable in the wire and by how much voltage drop is acceptable between one end of the wire and the other. The heating limit of the wire sets the allowable power loss per unit length. Since wires have resistance, the power loss in the wire is … Webb17 apr. 2015 · What you call the "time constant" of the charging path, isn't constant: it depends on supply voltage.

WebbNow I think I properly understand why the voltage rises slowly after the leading edge of a pulse--the capacitor acts like a variable-resistor turning the circuit into a voltage divider. R1 delays the time it takes to charge the capacitor, and while it accumulates charge, its resistance slowly increases, changing the balance in the voltage divider to increase the … Webb4 mars 2024 · Assume the resistance of the device remains the same (2.5 ohms) since no changes were made to it. The power supply voltage now changes from 5 V to 20 V, which means that the device must now dissipate 20 V squared divided by 2.5 ohms = 400/2.5 = 160 watts! Fortunately, your new adapter can only supply 20 V * 2 A = 40 W of power.
