I got tired of switching the leads of my DMM. Suddenly if dawned on
me that I can just set the power supply to 10.0V for exaample, and read the current, and then divide the voltage by the current to find the resistance. Like I put a resistance on the PS, it reads 10.0V and the current is .018A, so 10 / .018 gives 555.6 ohms. Must be a 560 ohm resistor. I turned my PS into an ohmmeter - FREE! Hee-hee - Work smarter, not harder! Of course, make sure the current stays low so the resistance doesn't overheat. For low resistances use a volt or less. -- @@F@r@o@m@@O@r@a@n@g@e@@C@o@u@n@t@y@,@@C@a@l@,@@w@ h@e@r@e@@ ###Got a Question about ELECTRONICS?
