you can use the R motor from a hard drive. note this motors don't work for testing current.

Convortion of moving coil galvanometrr into voltmeter?
A galvanometer can be converted into a voltmeter by connecting it with very high resistance.
What does a voltmeter measure voltage in?
A voltmeter measures voltage in volts.
What does electromagnetism have to do with galvanometer?
A galvanometer is a simple meter that detects the flow of current. A current flowing in a wire causes magnetism around the wire. This is called electromagnetism. Like poles of a magnet repel and opposites attract. The Galvanometer uses these principles in order to move a pointer across a scale.
Why damping is small in ballistic galvanometer?
to get critical damped system
What is an ac voltmeter?
A: It is a regular DC voltmeter but the AC is rectified and the DC component is measured and displayed as AC VOLTS.
Difference between galvanometer and voltmeter?
Galvanometer is similiar to ammeter which is used to detect small current through it whereas a voltmeter measures the potential difference in a cicuit..
Convortion of moving coil galvanometrr into voltmeter?
A galvanometer can be converted into a voltmeter by connecting it with very high resistance.
A galvanometer can be converted into a voltmeter by placing?
a high resistance in series
What resistance value is add to convert a galvanometer into a voltmeter?
It depends on the resistance of the galvanometer and the current required to reach full scale. A 100 ohm meter requiring 1 milliampere would require 99.9 KOhms in series to become a 100 volt voltmeter.
High resistance in parallel connected with galvanometer to form voltmeter?
That won't work. To convert an ammeter (a galvanometer is a very sensitive type of ammeter) you connect a high value resistor in series with it.
Steps in making a galvanometer?
A galvanometer is used to test an electrical current. A galvanometer can be made using a compass and a thin gauge of wire.
Symbols of the electric circuit?
there is a symbol of bulb,galvanometer,voltmeter,ammeter,gong,paperclip,switch,wire,solenoid,bulb and armature
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.
What value of resistance is used to convert galvanometer into voltmeter?
It depends on the resistance of the galvanometer and its full scale current. A 100 ohm meter reading 1 milliampere would require 0.1 volts to reach full scale, so it would require about 0.1 ohms in parallel to become a 1 ampere ammeter.
How do you measure volts?
By using a voltmeter.
How do you convert galvanometer to an ohmmeter?
"An ohmmeter is an electrical instrument that measures electrical resistance, the opposition to an electric current."The unit of measurement for resistance is ohms (Ω).It is useful device for rapid measurement of resistance. It is consist of galvanometer and adjustable resistance Rs of known value and a cell connected in series. The resistance R to be measured is connected between the terminals.The series resistance Rs is so adjusted that when the terminals are short circuited i.e., when R = 0, the galvanometer gives full scale deflection. So the extreme graduation of the usual scale the galvanometer is marked 0 for resistance measurement. When terminals are not joined no current passes through the galvanometer and its deflection will be zero . Thus zero of the scale marked as infinity. . When R is not infinite , the galvanometer deflects to some intermediate point depending on the value of R scale can be calibrated to read the resistance directly.
How voltage measured?
It is measured using a Voltmeter
