∙ 12y agoAny galvanometer is a type of ammeter: and is a devise that is used for detecting and measuring an electric current. In essence, they are electromechanical(electrically operated mechanical device)transducers (transducer is a device that converts one type of energy to another) that produce rotary deflections of an analog pointer whenever there is an electric current flowing through its coil. Specifically, a ballistic galvanometer is used to measure flux and current and is a type of mirror galvanometer. On this type of devise the moving part has a large moment of inertia (compared to current-measuring galvanometers) and, as such, has a long oscillation period. At its essence it is an integrator (a device used to perform the mathematical operation known as integration, an operation in calculus) used in measuring the quantity of charge discharged through it.

But a B.G measures charge due to impulse in the coil (sudden flow of charges for a short interval of time).

What are the readings for the experiment - to convert a galvanometer int ammeter?
A galvanometer is a type of ammeter an instrument for detecting and measuring electric current. A galvanometer can be converted into ammeter by connecting resistance in parallel with it.
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.
Does interchanging the galvanometer ad battery in a wheatstone bridge affect the balance?
No.AnswerWork it out, yourself, from first principles. Start with the assumption that, for the bridge to be 'balanced' (i.e. with no current flowing through the galvanometer), the potential-difference across the galvanometer is zero. It is quite simple.
What is the proper placement of an ammeter in a circuit?
Ammeter should be inserted in the place where we need to find the current. Care must be taken while inserting ammeter such that it is in series always. For example if we need to measure the current through any device, we have to connect the ammeter in series with tht device.
What is a NULL Point of a galvanometer?
Its a point on the galvanometer where the galvanometer shows no deflection as no current passes through it.
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..
How you convert galvanometer into ammeter in detail?
By attaching a resistance in parallel connection with the galvanometer. Or when a low resistor connected in parallel with galvanometer ,the galvanometer is converted in ammeter. and the resistor is called shunt resistance.
What are the readings for the experiment - to convert a galvanometer int ammeter?
A galvanometer is a type of ammeter an instrument for detecting and measuring electric current. A galvanometer can be converted into ammeter by connecting resistance in parallel with it.
What is the difference between the construction of a moving coil galvanometer and a ballistic galvanometer?
What is the difference between the construction of a moving coil galvanometer and a ballistic galvanometer?
How can you convert galvanometer into ammeter?
Since Galvanometer is a very sensitive instrument therefore it can't measure heavy currents. In order to convert a Galvanometer into an Ammeter, a very low resistance known as "shunt" resistance is connected in parallel to Galvanometer. Value of shunt is so adjusted that most of the current passes through the shunt. In this way a Galvanometer is converted into Ammeter and can measure heavy currents without fully deflected.
Name the instrument used to measure electric current?
A magnetic compass can detect current, butyou'll need an Ammeter to measure it.A galvanometer can detect current ~ butyou'll need an Ammeter to measure it.
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 is a galvanometer called when calibrated to read current?
That would be an ammeter.
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.
What kind of meter is created when is shunt is added to a galvanometer?
A galvanometer with a low resistance shunt in parallel makes an ammeter.
Moving coil galvanometer converted into a multi range ammeter?
yes
What instrument is used in a lab to measure electrical cureent?
Either an ammeter or a galvanometer is.
