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.
What else can I help you with?
Why damping is small in ballistic galvanometer?
to get critical damped system
Where and when did Michael Faraday invent Electromagnetism?
Michael Faraday did not invent or discover electromagnetism. After Hans Christian Oersted discovered it he simply studied it more.
A moving coil galvanometer can be used as an ammeter by adding?
a series resistence with its coil
How does Faraday's Law by Michael Faraday fit into the show LOST?
Well, M. Faraday studied electromagnetism, and electromagnetism plays a big role in Lost.
Convortion of moving coil galvanometrr into voltmeter?
A galvanometer can be converted into a voltmeter by connecting it with very high resistance.
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?
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.
Does a galvanometer have a reversed current or not?
The current is reversed in a galvanometer
Is it correct to say that an electric motor is a simple extension of the physics that underlies a galvanometer?
Yes, it is correct to say that an electric motor is a simple extension of the physics that underlies a galvanometer. Both devices operate based on the principles of electromagnetism, where electrical current interacts with magnetic fields to produce motion. The key difference is that a galvanometer is designed to measure small electrical currents, while an electric motor is engineered to convert electrical energy into mechanical motion for performing work.
What is galvanometer constant and how to find it?
The galvanometer constant is the factor that relates the deflection of a galvanometer to the current passing through it. It is usually given as the current required to produce a unit deflection (such as one full-scale deflection) on the galvanometer. To find the galvanometer constant, you can pass a known current through the galvanometer and measure the corresponding deflection, then calculate the constant as the current divided by the deflection.
Why do you need to set a galvanometer to 0?
Zero is the normal position of the galvanometer when there is no detection in process.
Which circumstances would a current register on the galvanometer?
A current would register on a galvanometer when there is a flow of electric charge through the circuit that the galvanometer is connected to. The galvanometer measures the strength and direction of the current passing through it, displaying this information as a deflection on its dial.
Does galvanometer have polarity?
No, a galvanometer does not have polarity. It is a device used to detect and measure small electric currents. The deflection of the needle in a galvanometer indicates the presence and direction of the current but not the polarity.
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.
Why galvanometer are used in electronic instruments that measures low current and voltage?
The galvanometer is very sensitive.
How do you convert galvanometer to ohmmeter?
Ohms are the unit of measurement for resistance, so an ohmmeter is a device that measures electrical resistance. A galvanometer measures the current flowing through the resistance, so the two are related. To convert a galvanometer into an ohmmeter, one needs an external battery.
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.
