What are the disadvantages of a moving coil galvanometer?
major disadvantage is that moving coil galvanometer is not suitable for a.c measurement
What is weston galvanometer?
The weston type galvanometer is a moving coil galvanometer in which a pointer is attached to the coil for measuring deflection due to torque .
Moving coil galvanometer converted into a multi range ammeter?
yes
Why is it necessary to have some form of controlling couple in the moving coil galvanometer?
To stop the moving coil from movement as if there wasnt any opposite couple the coil will complete rotating and this wouldnt help measurement.
How a galvanometer works?
Electricity passing through a wire coil creates a magnetic field which twists a suspended magnet and mirror. A light beam reflects off the mirror and onto a scale.
What is the difference between the construction of a moving coil galvanometer and a ballistic galvanometer?

Write the construction of a moving coil galvanometer?
A moving coil Galvanometer consists of a coil PQRS which is wound over a non metalic frame having soft iron core in the middle. This Coil Is suspended in b/w a powerful magnet poles N-S with the help of Phosphor Bronze wire. Concave mirror is fixed on d suspending thread upside the coil through which deflection can b noted by Lamp and Scale arrangement. The lower end of the coil is connected by hair spring.

A moving coil galvanometer can be used as an ammeter by adding?
a series resistence with its coil
What will happen in the absence of iron cylinder in a moving coil galvanometer?
it will not work
Moving coil galvanometer converted into a multi range ammeter?
yes
What is coil galvanometer meter and its application?
Moving coil galvanometre is a device which is used to detect current in a curcuit.
Working of moving-coil galvanometer?
A moving coil galvanometer is a type of scanning device used in the transportation and trucking industry. The vehicle is pulled through a fixed scanner while an operator watches a closed circuit television.
Why is it necessary to have some form of controlling couple in the moving coil galvanometer?
To stop the moving coil from movement as if there wasnt any opposite couple the coil will complete rotating and this wouldnt help measurement.
What are the important questions in intermediate first year physics?
moving coil galvanometer
Can moving coil galvanometer be used to detect ac in a circuit give reason?
Moving coil galvanometer is used to detect unknown resitance of the both ac or dc circuits :)deepak instrumentation engineerAnswerA 'galvanometer' is simply an instrument that detects and measures small currents; 'moving coil' describes its operating principle. A moving-coil galvanometer is a d.c. instrument; if subject to a.c., then it will simply vibrate as it will not be able to respond the the frequency (unless the frequency is very low, in which case, it will sweep back and forth in step with that frequency).The moving-coil principle is applied to other instruments, and can be used in the construction of multimeters. In the case of a multimeter, a rectifier circuit is incorporated so that it can be used to measure a.c. currents and voltages.
