Re: [Electrical] Electrical problem

Let's try this

Switch closed - zero ohms
Switch open - infinite ohms

If you close your switch and put an ohmmeter in place of the battery will you get "O" ohms? I don't hardly think so. The wire and lamp both have resistance that will read.

But

If you open the switch the ohmmeter will not read any ohms so the value is zero.

So by the same logic if you measure 120V on the 2V range of your multimeter and get no reading it means that the voltage is 0?
Don't think so.
No reading means resistance higher than the selected range of the multimeter. NOT zero.
