It depends upon factors such as the needed voltage range, input impedance, accuracy, and temperature sensitivity. For some purposes, a multimeter (which will also measure current and resistance) costing under $10 can be found online at sources such as Amazon. Laboratory instruments can cost thousands of dollars.

How do you test 220 volts using a volt meter?

Make sure that the test meter is on the correct voltage scale. Place one lead on one of the conductors to be tested and the other lead on the other voltage source conductor. The reading you obtain will be the voltage potential between the two conductors.


Describe how a meter would be connected in a circuit too measure the voltage at a light bulb?

When connecting a volt meter to a light bulb to measure the voltage of the light bulb, run a third wire from where the wire enters the bulb to one terminal of the voltmeter and a fourth wire from the other side of the bulb to the other terminal of the voltmeter.


How does an ohm meter work to measure electrical resistance?

An ohm meter works by sending a small amount of electrical current through a material and measuring the voltage drop across it. By using Ohm's Law (VIR), the meter can calculate the resistance of the material based on the current and voltage readings.


How much voltage does each branch of a parallel circuit?

Yes. The voltage across every branch of a parallel circuit is the same. (It may not be the supply voltage, if there's another component between the power supply and either or both ends of the parallel circuit.)


How do you meter a 208v load meter only 1 phase add the two?

The voltage 208 is a three phase voltage. Single phase is classed as the voltage obtained from any two legs of the three phase voltage system. The voltage between L1 to L2 = 208. L2 to L3 = 208 volts and L3 to L1 = 208 volts. To measure the load of the 208 volt device just clamp an amp meter around one of the legs coming from the load. This will give you the amperage that the load draws.
