The … WebMar 31, 2015 · An effective way to cut down the inrush current is to increase the resistance on the capacitor-charging path – inserting a resistor like that shown in Figure 3. If you insert a 2.5Ω resistor, the inrush current can easily be cut down below 70A at a 120V AC input. But if you insert a 2.5Ω resistor in a 200W power supply for current-limiting ...

WebSo the current is lower for a high resistor because it lets fewer charge through it per second, not because the electrons intuitively "know" which path has least resistance. Electrons will go through every path, but lower resistance means some paths will let electrons through at a higher rate and therefore have a higher current. WebAdd a Motor and Transistor.
