WebJun 13, 2024 · It limits the current by behaving like a resistor; Are there some resistors set up in series in order to cut down the current flow before it actually reaches the device? The relevant resistor is the device itself, but there is a resistor in series that reduces the current flow a little. It is the wire itself. 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.
