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.
What is deadbeat galvanometer?
When current is passed throgh a galvanometer, the coil oscillates about its mean position before it comes to rest.To bring the coil to rest immediately, the coil is wound on a metallic frame.Now, when the coil oscillate, eddy currents areset up in the metallic frame, which opposes further oscillations of the coil.This inturn enables the coil to attain its equilibrium position almost instantly.Since the oscillation of the coil die out instantaneously, the galvanometer is called dead beat galvanometer.
What is the role of the soft iron core?
In a moving coil galvanometer, soft iron core intensifies the magnetic field through it. this causes maximum number of magnetic field lines to pass through the coil.
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 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 .
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.
Convortion of moving coil galvanometrr into voltmeter?
A galvanometer can be converted into a voltmeter by connecting it with very high resistance.
Can moving coil galvanometer be used to detect an alternating current in a circuit?
no. it,s only used to measure D.C
