What is galvanometer and how a galvanometer converted into an 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.
Function of galvanometer?
A galvanometer is an instrument used for detecting electric currents.
How do you find resistance of a galvanometer?
Measure the voltage across the terminals and read the current from the galvanometer at the same time.
Why do you connect galvanometer in series?
You connect a galvanometer in series with the circuit being measured, because the galvanometer is a form of ammeter, although an extremely sensitive one, and ammeters measure the current in a series circuit.
If null is compared with null what is the result-true or false or null or unknown?
You mean SQL? NULL = anything IS NULL NULL <> anything IS NULL ... NULL IS NULL = TRUE NULL IS NOT NULL = FALSE
What is null point?
Null point is the point in which the gravitational force between moon and the earth is equal in opposite direction. So there is no effect of any force.
What does the mid point mean in a graph?
null
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 unstable galvanometer?
Galvanometer that cannot die out oscillations instantaneously or quickly is called unstable galvanometer.
Disadvantages kelvin double bridge?
requires manual balancingsensitive null detector or galvanometer is required to detect balance conditionmeasurement current needs to be reasonably high to achieve sufficient sensitivity.
What is galvanometer and how a galvanometer converted into an 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.
Does a galvanometer have a reversed current or not?
The current is reversed in a galvanometer
Why tangent galvanometer is called tangent galvanometer?
because in tangent galvanometer earth magnetic field and magnetic field of magnet inside galvanometer are perpendicular to each other
What does a galvanometer measure?
galvanometer is a device use to measure current.
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.
How do you convert galvanometer to ohmmeter?
To convert a galvanometer to an ohmmeter an external battery is attached in series with galvanometer. This will drive a current through an external unknown resistance and measure the resulting current using the galvanometer.
Steps in making a galvanometer?
A galvanometer is used to test an electrical current. A galvanometer can be made using a compass and a thin gauge of wire.
