How can we convert galvanometer into voltmeter and ammeter?
An ammeter is an instrument used to measure the current passing through a circuit. A galvanometer can be converted into ammeter by connecting a low resistance called shunt in parallel to the galvanometer. A voltmeter is a device used to measure the potential difference between two points in a circuit.
How do you convert galvanometer into voltmeter?
A galvanometer can be converted in to a voltmeter by connecting a high resistance in series connection within it. The scale is calibrated in volt. The value of the resistance connected in series decides the range of the voltmeter. The resistance is calculated by this equation which is connected in series.
How do you convert a galvanometer into an ammeter explain?
A galvanometer is converted into an ammeter by connecting a low resistance in parallel with the galvanometer. This low resistance is called shunt resistance S. The scale is now calibrated in ampere and the range of ammeter depends on the values of the shunt resistance.
What is a shunt How do you convert a galvanometer into ammeter and voltmeter explain it?
A galvanometer is converted into a voltmeter by connecting a high resistance ′R′ in series with it. A galvanometer is converted into ammeter by connecting a small resistance (called shunt) in parallel with it. Resistance of voltmeter, Rv=G+R.
Can a galvanometer be converted into ammeter Class 10?
An ammeter is made from a galvanometer. Or we can also say that a galvanometer can be converted into an ammeter. To convert a galvanometer into an ammeter, we connect a resistance R parallel to the galvanometer. This resistance is called shunt resistance.
Can a galvanometer be used as a voltmeter?
A galvanometer can be converted into a voltmeter by connecting a large resistance in series to the galvanometer which is shown in diagram. Resistance of an ideal voltmeter is infinite. A voltmeter is always connected in parallel to the circuit component across which voltage is to be measured.
How do you convert a voltmeter to ammeter?
The first step to convert a voltmeter to an ammeter is to determine the resistance Rm of the voltmeter. Make the circuit connections as shown in Fig 2(a). 2. Keeping R = 0, adjust the supply voltage E so that the voltmeter shows large readings Vm.
What is the formula of voltmeter and ammeter?
The reading of the voltmeter can be determined by finding the potential difference across the 2Ω resistance by using the value of current in the circuit. V=IR, here V is the potential difference across a resistance R through which a current I is flowing. The ammeter is connected in series with the circuit.
Can an ammeter be used to measure voltage?
An ammeter is a measuring device used to measure the electric current in a circuit. A voltmeter is connected in parallel with a device to measure its voltage, while an ammeter is connected in series with a device to measure its current.
Can a galvanometer be converted into an ammeter and voltmeter?
A galvanometer is a very sensitive device that can detect the small currents and it can be easily converted into an ammeter and a voltmeter. However, the conversion of galvanometer into ammeter and voltmeter requires a good study on interconnection because galvanometers are very sensitive instruments for detecting the current.
What are the components of a galvanometer?
Apparatus : A Weston type galvanometer , a voltmeter of 0-3 V range , a battery eliminator , two resistance boxes , the one way key , a rheostat , connecting wires .
How to calculate the shunt resistance of a galvanometer?
For the conversion of a galvanometer into an ammeter of range ‘I’, we require a shunt resistance and it can be calculated by the following formula: S = (Ig * G)/ (I – Ig) I m a g e w i l l b e U p l o a d e d S o o n
How is water flow measured using a galvanometer?
The energy/push given for the water supply is the potential difference and the measure of the same is done by a voltmeter. If the waterfalls in minute drops (small electric current), then this water flow is measured by a galvanometer. The conversion of galvanometer into voltmeter is done by adding a highly-resistive multiplier in series.
