Which type digital voltmeter is the of fatest all digital voltmeter?
You mean fastest? Digital voltmeter gives reading in seconds.
What causes an error in reading a voltmeter?
It could be when the positive wire is plugged in the negative slot and the negative wire is plugged in the positive slot. This can make the readings negative.
What is the voltmeter reading this time?
positive terminal
Will the rusting of nails in a sodium chloride - water solution effect the reading off a voltmeter or ammeter?
An ammeter or a voltmeter gives the reading of the flow of current, which is due to the movements of ions. When a rusted nail is immersed in the solution it will add the no of ions into the solution. This will increase the ion concentration and therefore will change the reading of a voltmeter and ammeter.
What is the function of a voltmeter in an electrical circuit?
To measure Voltage which is the force pushing current :)
What is the significance of obtaining a negative reading in testing voltage?
Electric current can flow in one of two directions in a wire; with alternating current, the direction changes continually, back and forth. The use of positive and negative values for voltage gives you a direction for the voltage. If current flowing to the right is positive, then current flowing to the left is negative.============================Answer #2:A negative reading indicates that the point to which the positive probe ofthe voltmeter is connected is at a lower potential than the point to whichthe negative meter probe is connected. It tells nothing about the circuitconditions except in combination with the knowledge of how the meteris connected.
A multirange voltmeter which scale is numbered from 0 through to 250 the pointer falls mid range on the scale interpret the reading on the meter?
With the pointer mid range on the scale, the reading of the multi-range voltmeter would be 125 volts.With the pointer mid range on the scale, the reading of the multi-range voltmeter is 125 volts.
What happens if you accidentally connect the positive lead of a voltmeter to the negative terminal of a 1.5 volt battery and the negative lead to the positive terminal?
Voltmeter will give you opposite readings or will not work at all.
Basic difference bet ac and dc?
If you measure the Instantaneous Volyage using a Voltmeter the1. DC the Voltmeter reading will remain constant it will not change.2. AC the voltage will vary from positive to negative . The variation can be sine wavw, Square wave, triangular wave or any other type.
A 100 V voltmeter has full scale accuracy of 5 percent At its reading of 50 V it will give an error of?
A 100 V voltmeter has full-scale accuracy of 5%. At its reading of 50 V it will give an error of
What is false pregnancy symptoms?
Usually a false pregnancy means that you have taken a pregnancy test and it gives you a positive reading when you are not pregnancy (which is very rare) or a negative reading when you really are pregnant.
Is ther a negative and a positive probe in a voltmeter?
Yes, the black probe is the negative one (kathode) and the red probe is the positive one (anode)
