Why galvanometer are used in electronic instruments that measures low current and voltage?
The galvanometer is very sensitive.
While transporting sensitive galvanometer the terminals are?
connecting the damping resistance across the terminals
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.
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.
What is the ideal internal resistance of galvanometer?
zero
Why galvanometer are used in electronic instruments that measures low current and voltage?
The galvanometer is very sensitive.
Why A sensitive galvanometer cannot be stable?
A sensitive galvanometer is highly responsive to small changes in current, making it prone to disturbances from external factors like temperature fluctuations or electromagnetic interference. These disturbances can cause fluctuations in the readings of the galvanometer, leading to instability in its output. Additionally, the delicate construction of a sensitive galvanometer can make it more susceptible to mechanical vibrations or shocks, further affecting its stability.
Why galvanometer called sensitive instrument?
A galvanometer is called a sensitive instrument because it is capable of detecting even small currents passing through it. Its design allows for precise measurement of small electrical currents, making it highly sensitive to changes in current flow.
While transporting sensitive galvanometer the terminals are?
connecting the damping resistance across the terminals
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.

How is a galvanometer similar to a motor how is it different?
A galvanometer and a motor both have coils in a magnetic field, but they serve different functions. A galvanometer is used to measure small electric currents, while a motor is used to convert electrical energy into mechanical motion. The main difference is that a galvanometer typically has precise and sensitive measurement capabilities, whereas a motor is designed for generating rotational movement.
While transporting a sensitive galvanometer?
Make sure to handle the galvanometer with care to avoid damaging sensitive components. Keep it secured and protected during transport to prevent any jarring movements that could affect its calibration. Consider using shock-absorbing materials or packaging to minimize the risk of damage.
What is the difference between a galvanometer and an ammeter?
A galvanometer is a device used to detect small electric currents, while an ammeter is a device used to measure the strength of electric currents. The main difference is that a galvanometer is more sensitive and used for detecting small currents, while an ammeter is used for measuring larger currents.
What is weston galvanometer?
A weston galvanometer is a type of sensitive instrument used to detect and measure small electric currents. It uses a moving coil suspended in a magnetic field to deflect in response to the current passing through it. This deflection is then used to indicate the strength of the current.
Moving coil galvanometer converted into a multi range ammeter?
To convert a moving coil galvanometer into a multi-range ammeter, you can add shunt resistors of different values in parallel to the galvanometer. By selecting the appropriate shunt resistor, you can change the range of the ammeter. This allows the ammeter to measure a wide range of currents while still using the sensitive galvanometer as the measuring element.
