False. The instrument is called an oscilloscope. (Human Physiology, 11th Edition, Stuart Ira Fox. Chapter 7, pg 170, paragraph 5.)

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.
How you could determine the amount of energy stored in one potato chip?
I'm pretty sure there aren't any, but if you want to find out, you could get a voltmeter and connect both ends of the voltmeter to either side of the chip. Besides, what could you possible do with the amount of energy stored in a potato chip. If you're doing this for a science project, I would come up with a new idea if I were you. No offense.
Which meter creates an alternate path for the electrons to follow?
Both a voltmeter, and the internal guts of an ammeter, establish a parallel path around a component or a part of a circuit when they're connected to it for the purpose of making a measurement.
How can you produce current from salt water?
An electric current can be made simply by dipping two different metals into the salt water so that they are not touching each other. You can try this with a "copper" coin and a "silver" coin and measure a small voltage between them using a voltmeter, but you will get a better result by using a piece of pure copper and a piece of pure zinc which should give a voltage of about 1 volt.
What is the difference between an indicator and a universal indicator?
A pH meter uses a probe and voltmeter to measure pH digitally. Universal indicator is a mix of indicators that change colour to indicate the pH of the solution. pH meters are accurate and will detect changes quickly, whereas universal indicator is slow to change colour to indicate pH change.
What is voltmeter?
A voltmeter is a measuring instrument that is used in the measurement of the electric potential in volts.
What instrument measures electric potential?
Voltmeter, potentiometervoltmeterVoltmeter
What is a voltmeter?
a calibrated instrument for measuring the potential difference between two points.
What is the meaning of voltmeter?
An instrument for measuring in volts the differences of potential between different points of an electrical circuit.
Which instrument can measure static electricity having a potential difference as low as 0.1 volts?
electroscope
The function and use of an ammeter and a voltmeter?
A: ACTUALLY they are both the same just the application makes one or the other. Their function is to measure potential difference on a load or circuitry
How do you measure electric potential?
A voltmeter is an instrument used to measure electric potential difference. The voltmeter have two electrodes, reference electrode and test electrode, the electrodes are put in two different places where you want to find the potential difference. For instance, if the test electrode is placed on the positive pole and the reference electrode on the negative pole of a 3V battery, the voltmeter would read '+3 volts'.
What is instrument specially designed to measure voltage?
The Ammeter XD
What instrument measures VDC?
A DC voltmeter is ideal.
What instrument measures electrical pressure in a circuit?
A voltmeter
What instrument used for measuring the voltage difference?
A VoltMeter
What measuring instrument is used to measure potential difference?
To Measure Voltage or potential difference you can use volt meter, there are diferent methode to measure DC voltage and AC Voltage.use a AVO meter and you can choose Voltage in each voltage range on the selector.a Volt meter instrument you can find it by manual methode and digital .Dont forget to read manual book before you will measure the voltage.Comment'Potential difference' is exactly the same thing as 'voltage'; they are synonymous.
