What is unstable galvanometer?
An unstable galvanometer is a type of instrument that is sensitive to external disturbances such as temperature changes, magnetic fields, and vibrations. This sensitivity makes the measurements taken with an unstable galvanometer less reliable and accurate compared to stable galvanometers. Unstable galvanometers are often used in situations where extreme sensitivity is required, but precautions must be taken to minimize external influences.
What will happen in the absence of iron cylinder in a moving coil galvanometer?
it will not work
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 can happen when a fire becomes unstable?
When fire becomes unstable, it becomes disastrous. It is difficult to handle it.
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
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?
To convert a galvanometer into an ammeter, you need to connect a low resistance in parallel with the galvanometer. This low resistance is called a shunt resistor. By selecting the appropriate shunt resistor value, you can calibrate the galvanometer to accurately measure higher currents. The formula to calculate the shunt resistor value is Rs = G * (Imax/Ig - 1), where Rs is the shunt resistor value, G is the resistance of the galvanometer, Imax is the maximum current the ammeter will measure, and Ig is the full-scale current of the galvanometer.
Why galvanometer are used in electronic instruments that measures low current and voltage?
The galvanometer is very sensitive.
