One ohm is a particular reading on the ohms scale of a multimeter. It corresponds, per Ohm's Law, to the resistance that a current of one ampere would cause a potential difference of one volt across. (Or one millampere and one millivolt, however it happens to scale.)

How can I test a dryer thermostat to ensure it is functioning properly?

To test a dryer thermostat, you can use a multimeter to check for continuity. Disconnect the thermostat from the dryer and set the multimeter to the ohms setting. Place the multimeter probes on the thermostat terminals and check for a reading of zero ohms, indicating continuity. If there is no reading, the thermostat may be faulty and needs to be replaced.


What is infinity ohms?

Infinite ohms is what a multimeter will read across an open switch or a broken connection. It means that no electrons will pass between the points being measured.


How can I perform a test on a dryer thermostat to determine if it is functioning properly?

To test a dryer thermostat, you can use a multimeter to check for continuity. Disconnect the thermostat from the dryer and set the multimeter to the ohms setting. Place the multimeter probes on the thermostat terminals and check for a reading of zero ohms, indicating continuity. If there is no reading, the thermostat may be faulty and in need of replacement.
