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.
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.
What is Construction of moving coil ballistic galvanometer?
A moving coil ballistic galvanometer is a sensitive instrument used to measure small amounts of electric charge. It consists of a coil of wire suspended between two pole pieces of a permanent magnet. When a current passes through the coil, it experiences a torque and deflects, allowing the measurement of charge.
Why you put coil in nonmetallic frame not in metallic frame in ballistic galvanometer?
A nonmetallic frame is used for a ballistic galvanometer to prevent damping of the coil movement by eddy currents induced in a metallic frame. This allows the coil to move freely and respond accurately to the changing magnetic field, making the instrument more sensitive and accurate in measuring current pulses.
What is unstable galvanometer?
An unstable galvanometer is a type of instrument used to measure small electric currents. It is called "unstable" because its sensitivity varies with the position of its moving coil, making it difficult to obtain accurate and consistent readings. This type of galvanometer is often used in applications where precise measurements are not critical, such as in educational settings or for qualitative analysis.
How is a galvanometer sensitive?
GALVANOMETER detects very small currents in terms of milli amperes so it is said to be called as sensitive
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.
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 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.
What is the instrument called that measures current?
The instrument used to measure electrical current is called an ammeter, which is actually a shortened form of 'amp meter'. The current is measured in amperes. In scientific labs, a much more sensitive instrument called a galvanometer is used to measure very small currents.
What instrument is used to measure electric?
A galvanometer or milliammeter.
What instrument is used to measure electric current?
A galvanometer or milliammeter.
What instrument measures current flowing through wires in a house?
galvanometer
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 instrument is used in a lab to measure electrical cureent?
Either an ammeter or a galvanometer is.
How is the flow electricity of electricity mearsure?
flow of electricity is measured by an instrument galvanometer
