To be specific, a voltmeter is a tool used especially in science to calculate the differences of electric potential of two circuits. There are quite a few types of voltmeters and they are also quite portable which may be ideal for traveling with.

How do you convert voltmeter to ohmmeter?
First you will need a constant current source. Do NOT connect the voltmeter to the constant current source without the resistor to be measured already connected. Do NOT use a battery, it is a voltage source. Then follow these steps to measure a resistor:connect the voltmeter across the resistor to be measuredconnect the voltmeter-resistor combination across the constant current sourceread the voltmeter and record the voltagedisconnect the voltmeter-resistor combination from the constant current sourcedisconnect the voltmeter from the resistorcalculate the resistance from the measured voltage and current from the source with Ohm's law in this form: R = V ÷ IIts much easier to just use the ohms setting on a multimeter.
What is the use of universal high resistance voltmeter?
A voltmeter must have a very high resistance to measure voltage. A voltmeter is placed in parallel with the element that you are measuring. If the voltmeter has a low internal resistance, then all of the current will flow through the voltmeter instead of the element. You want all of the current to flow through the element, to get an accurate reading of the voltage. Conversely, an ampmeter must have zero resistance, because it is placed in series with the element.
What is the use of the oscilloscope?
If you use a voltmeter to observe a voltage, it can only respond slowly, so if you want to observe a voltage that changes in fractions of a microsecond, you need a voltmeter that can respond at such speeds. It is called an oscilloscope.
What is used to monitor line voltage sag?
An AC voltmeter is ideal. If you really want to get fancy and analytic about it, you could use data-acquisition equipment to constantly read the AC voltmeter, and store or record the data.
What is the voltmeter reading this time?
positive terminal
How do you measure EMF?
Use a voltmeter.
What careers use voltmeter?
electricians.
What do we use to test Voltage?
A voltmeter
What is the use of digital voltmeter?
the voltmeter use a SLR camera because this is the latest camera and the good light and good shot of a picture
Why cant you use voltmeter 2 calculate emf of a cell?
because voltmeter is used to measure the voltage
How do you measure the voltageof a lightbulb?
You can use a voltmeter.
How is voltage measured?
Use a voltmeter with a high input impedance and measure at the source the voltage.
What do you use to measure voltage in an electronic circuit?
A Voltmeter.
What can you use to identify large electrical currents?
A voltmeter
What can you use to check the voltage of a battery?
Voltmeter or multimeter.
To measure EMF you would use a(n)?
"voltmeter"
What is a use of a voltmeter?
A voltmeter is used to measure the difference in electric potential ("voltage") between two points, usually but not necessarily in an electrical circuit..
