Let me begin, by saying I didn't know there was a homework help forum here. I am taking an electrical course in appliances and refrigeration and there are a lot of questions on electrical troubleshooting. I have asked in other forums on this site and got some pretty good answers. I have another question that pertains to my homework, When testing for voltage, 120, across a switch or a timer, (and I am assuming a timer is the same as a switch,) to a load, would the reading read the same as just testing across the switch without the load. If open would it be 120 on the meter and closed 0 on the meter. I don't have a way to verify this, I have no equipment to work on, it is all guess work. Help appreciated.
