Question

Imagine that you've properly connected your multimeter into an operating circuit, and the meter's function/range switch is set to read DC voltage in the 20 V range. The meter displays a "1" in the most significant digit position. This indicates that

Answer 1

If the meter is set to  read DC voltage in the 20 volt range and it displays a 1 then it should mean 1 volt assuming that the maximum reading would be 20 volts at that setting. But if it is only around 1 volt is might be more accurate to set it at say 2V range to get say 1.6 actual volts.

Answer 2

Answer:

in this case The Voltage Is Greater Than 20 Volts

Explanation:

1 in that position means that your meter is giving a over range reading 20 dcv is the lowest setting you are suppose to keep going up on your meter until you run out of options if you still get the message it means the circut is open
