What is the principle of ballistic galvanometer?
The ballistic galvanometer principle states that when a current-carrying coil is suddenly disconnected from a source, the coil carries on moving because of its momentum. The deflection of the coil is proportional to the charge that passed through the coil while it was connected.
What are the construction of galvanometer?
galvanometer is an elctromechanical instrment which is used to indicate the current or voltage. principle of working-it works on the principle of conservation of electrical energy to mechanical energy.
What is the Similarities between a galvanometer and electric motor?
Both a galvanometer and an electric motor operate based on the principle of electromagnetic induction. They both have coils of wire that interact with a magnetic field to generate movement. Additionally, both devices can be used to measure or detect changes in electrical current.
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.
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.
Principle of multimeter?
Based on the principle of the D'Arsonval galvanometer, the main function of a multimeter is measuring a circuit's voltage, current, and resistance.
Two things which work on the principle of biotech and chemtech?
Two things which work on the principle of biotech and chem tech is a galvanometer apparatus and fire extinguisher.
What is a description of the principle of a meter bridge?
it work on the principal of balanced wheat stone bridge ..i.e the reading of galvanometer shows 0 ..
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 a NULL Point of a galvanometer?
Its a point on the galvanometer where the galvanometer shows no deflection as no current passes through it.
What are the construction of galvanometer?
galvanometer is an elctromechanical instrment which is used to indicate the current or voltage. principle of working-it works on the principle of conservation of electrical energy to mechanical energy.
Does a galvanometer have a reversed current or not?
The current is reversed in a galvanometer

What is the working principle of flame photometer?
The solution to be analyzed is discharged through atomizer to the chamber.The components get flamed and the light produced by the flame is absorbed through a optical sensor and causes change in the galvanometer which is attached to it.such that the change in the galvanometer is directly proportional to the concentration of the component being analyzed.

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.
