Hi i have a question and do not know the answer can you help me please

1 = If the function/range switch is set at 200 VAC, what will the multimeter read if a measurement is made directly across both terminal of a good fuse or circuit breaker in a 120 VAC line ?


2 = And what will it be of a Blown fuse or tripped circuit breaker in a 120 VAC line


What i think is 1 is 120 VAC
and 2 is 120 to because it's in the line
please enlighten me
Thanks in advance

Re: multimeter VAC question

What would the voltage be if you measured between two points on the same conductor in a 120 volt circuit?

If good far less than 1 volt,if over replace it.Keep reading them theory books you have long way to go :D it's kool your trying to learn

Re: multimeter VAC question

rawvie, think about Don's post, and apply it across the good fuse.

Hint: A fuse is only a weak link in a conductor. (this will make sense someday if it doesn't now)

In the second question draw it out, hot on one side, neutral on the other side, and put the meter probes around the opening in the circuit.

Re: multimeter VAC question

rawvie, you are welcome and welcome to the forum.

Stick around, there are some very helpful people here.

You may be asked to make the attempt on your own and then show your findings, but then you will be coached by some of the very best.

Re: multimeter VAC question

Rawvie,
Welcome to the form. I have a suggestion that may help. Look up the definition for a "Short" and look up the definition for an "Open" in regards to electrical circuits. When you find them don't just read them, understand them. Understanding why and how things happen is a big "Must Do" in this business, even the PC business ;) . Don't just take someone's word as to why you are doing something, research it, understand why you are doing it. This form will be a big help, it offers a lot of knowledge and very good people. If you take the time to read and understand what is being said, you will be head and shoulders above your class mates...........Just an apprentice's opinion. Good Luck with your studies.
