When I last worked with USB, there were all sorts of resistors over the pins telling you about its capabilities. I'm pretty sure usb-c has that as well. Your device should check the spec of the cable and inly draw the amount if power its rated for
- freeone3000 5y agoThere's a microcontroller in the cable negotiating the power transfer rate, data transfer rate, and other capabities.
- x0 5y agoIs a resistor really enough to determine if a 5W cable gets 240W?
- spookthesunset 5y agoCurrent is often measured by putting a small value resistor of a precisely known value and measuring its voltage drop. I = V/R
