What was the applications of galvanometer?
It can be used to form ammeter measuring the current intensity , Voltmeter measuring the potential difference , ohmmeter measuring the resistance.
How is electric resistence measured?
Resistance is usually measured using an ohmmeter, however if very high precision is needed a wheatstone bridge is used.
What are the difference between a multimeter and a voltmeter?
A multimeter measures electrical properties such as AC or DC voltage, current, and resistance. Rather than have separate meters, a multimeter combines a voltmeter, an ammeter, and an ohmmeter. The two main kinds of a multimeter are analog and digital. A voltmeter measures the potential difference (voltage) between two points. the voltmeter only measures volts.
What units is to meausure a ohmmeter?
An ohmmeter measures electrical resistance. This is one part of "impedance", that prevents electricity from flowing freely from one part of a circuit to another. Resistance is measured in "ohms".
What would be the voltmeter reading if the lamp across which it is placed has a broken filament?
A voltmeter connected across the broken (open) filament of a light bulb reads the full voltage of the power supply whether the bulb is in a series or parallel circuit. -- In a series circuit with other components in series with the bulb, this reading tells you that at least one of the components is open, possibly the filament. -- In a parallel circuit with other components in parallel with the bulb, or with the bulb connected directly to the power supply, this reading tells you nothing ... the voltmeter reads the full power supply voltage whether the bulb is open or good. The voltmeter isn't a very helpful measurement to identify an open filament. An ohmmeter, with the power to the circuit turned off, is much more helpful.
What are two familiar mistakes when using an ohmmeter and a voltmeter?
Voltmeter connect in parallel with the circuit setting on voltmeter highest range first then to lower range. Ohmmeter we need to use the ohmmeter meter setting connect across the resistor
What instrument measures voltage?
Resistance is measured with an ohmmeter. A link is provided to a brief article on the ohmmeter posted at Wikipedia.Note that it is unusual in this day and age to have a device that will measure ohms and nothing else. The ohmmeter is usually included among the functions of a multimeter, and usually a digital multimeter or DMM.
How is resistance measured?
it is measured in Ohmmeter Ohms
What is the purpose of multimeter in a laboratory?
it can be used as a ammeter, voltmeter and also as a ohmmeter.
What kind of meter uses its own battery?
A. ohmmeter B. voltmeter C. ammeter D. wattmeter
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 step is unique to connecting an ohmmeter in the circuit?
check the circuit with a voltmeter to make sure the circuit is not powered
What is the advantage provided by multimeter?
A multimeter, also called a VOM, is an ohmmeter, ammeter, and voltmeter combined in one case. A function knob can be turned to select the type of measurement to be made, such as volts, amps, or ohms. The multimeter's test lead connections to the circuit will depend on whether you are using it as a voltmeter, an ammeter, or an ohmmeter.
What instrument is used to measure the amount of electricity flowing through a circuit?
An ampermeter. -- voltmeter-- ammeter-- ohmmeter-- wattmeter-- frequency counterWe can't "measure electricity" unless we figure out what we are measuring. The difference of electrical potential is measured in units called volts, and a voltmeter is used to do that. The amount of electrical current flow is measured in units called amps (amperes), and an ammeter is used to for that purpose. A multimeter combines the functions of these two meters, and will most often include some other features to measure some other electrical characteristics. An example of another measuring function of a multimeter might be its use as an ohmmeter for measuring electrical resistance.im so bored

A current is measured in which unit?
The Ampere, also in shortened form 'Amp' or "A". It commonly uses the symbol "I" in calculations, hence Ohm's law is in the form V = I x R
When a needle of an analog ohmmeter indicates infinity the resistor being measured is?
Open
