Which of the following statements are not true of a moving-coil milliammeter? I. It can be used to measure alternating current II. It has a linear scale III. It can be adapted to read higher values of currents IV. A resistor connected in parallel with the milliammeter would convert it to a voltmeter
I and IV only
II and III only

a moving coil milliameter is also the same as moving coil meter or a galvanometer and also a common form of analog voltmeter.
•The moving coil millimeters is used to measure a very small amount of current,
•it has scale
•it uses a low resistance shunt connected in parallel, though its not specified here,they only said resistor but should know that its aow resistant shunt they meant
•Its never used to measure AC but DC
i can see comments from 6 years ago on this question, and till now no simple explanation has been provided. You can do better, MySchool.
note that iv is off it, because a resistance connected in parallel will not convert to voltmeter except its connected in series as stated earlier.
so on this note the correct answer here us E
go through the explanation very well,thus is what i arrived at.if you have any objection feel free to drop
It's not right because IV doesn't even come close. To convert a milliammeter into a voltmeter the multiplier is connected in series and not in parallel like the option IV is emphasizing.
