#190140 - Power rating of potentiometers |
A fixed resistor with a specification of 1000 Ohms / 1W can handle about 30mA maximum current.
Considering a potentiometer with the same rating - does the maximum current apply to both the winding as well as the wiper contact ? Or is the wiper contact rated higher to handle situations of zero resistance settings with no external reistor to limit current ? Raghu |

While I don't disagree ... there are different failure modes | 01/01/70 00:00 | |
