Could be more make sure measures DC. Can be anywhere from 10-about 15 on a car batt. for actual.

Why is it possible to measure an electric potential across the terminals of a dry cell?
Batteries are a voltage storage device that hold a voltage potential until used. By using a volt meter you can find the stored voltage by placing the leads of the meter across the battery's positive and negative terminals.
Should you use AC or DC to measure a dryers voltage?
The meter should be on the AC scale. In Canada and US the reading should be 240 on the outside blade holes and 120 volt from the outside blade holes to the center blade hole. The U shaped pin is the ground. No voltage from it to the center pin.
An ammeter and voltage range are measure the current and voltage electric lamp if mistake meter interchange what will happen?
1. Voltmeter has high impedance and hence will restrict the current severely.a) Electric Bulb will not glowb) The Ammeter will just measure the current that Voltmeter allows and since this current is much smaller than actual current nothing will happen to ammeter.c) The Voltmeter will measure the Voltage that is being applied.d) This will allow you to measure the resistance of the Voltmeter.VR=V/I
What are the types of electrodynamometer?
power meter,power factor meter, frequency meter, volt meter ,watt meter ,voltage ampere meter,
How do you measure conductivity?
With an AMPD meter using 1% voltage radar
What determine the polarity of the voltage across a resistor?
A: Current flow only one way form positive to a less positive point. However it is possible to measure negative and positive voltage drop it the meter leads are reversed.
How do you measure the voltage on a car alternator?
get a multi meter that reads dc voltage & touch the black (negative -) wire to the negative battery post & the red (positive +) wire to the positive battery post with car running. car off is battery voltage, car on is alternator voltage.

What is avo meter?
avometer comes from " avo " and "meter". 'A' means amperes, to measure electrical currents. 'V' means the voltage, to measure voltage. 'O' means ohms, to measure ohms or resistance. finally the meter or unit of measure. often reffered to as AVO meter multimeter or multitester. AVO meter is a device for measuring voltage, current, both AC and DC and electrical resistance.
What type of meter is used to measure voltage?
Voltmeter
Which meter used to measure the batteery voltage?
A voltmeter.
How do use a volt meter?
1. Attach the positive input terminal lead to the positive end of the circuit (or whatever you want to measure the voltage of). 2. Attach the negative input terminal lead to the negative end of the circuit (or whatever you want to measure the voltage of). The voltmeter will turn itself on and measure the difference between the voltage at the first point and the voltage at the second point, telling you how much voltage is traveling between the two points so that is how to use it effectivelly.
What is used to measure potential difference inparallel circuits?
A voltage test meter is used to measure voltage potentials in a circuit.
How do you measure alternating current voltage and resistance?
You measure current by inserting an amp meter in series with the circuit or using a clamp-on meter to measure current by induction. You measure voltage with a volt meter across the supply. You measure resistance in ohms across the resistance. Luckily all these functions are in the same meter in most cases.
What is The Function of Meter?
it is use to measure electric potential (voltage).
Why is it called multimeter?
since it stands for voltage ohm meter :) can measure voltage current and resistance
What is the function of potentio meter?
it is use to measure electric potential (voltage).
