to explain the operation of a spring-coil galvanometer
if the galvanometer having N coils that carry current kept in strong magnets
due to the coil rotates the rorque will be generated
that torque is = k
and
= N i A B
by equating
N i A B = k
/ i = N A B / k

423. In the illustration, a hollow coil of coated wire is connected to a galvanometer that measures small electric currents. A strong magnet moves to the left into the coil and through the coil, then exits the coil on the left. What would be the readings on the galvanometer? N S (A) The galvanometer would register a current in one direction as the (B) The galvanometer would register a current in one direction the entire (C) The galvanometer would register...
A coil of wire is connected to a galvanometer as shown. A magnet is held stationary above the coil. Under what circumstances will the galvanometer indicate a current?
A galvanometer with a coil resistance of 16.3 is used with a shunt resistor to make a nondigital ammeter that has an equivalent resistance of 0.817 . The current in the shunt resistor is 3.97 mA when the galvanometer reads full scale. Find the full-scale current of the galvanometer.
A galvanometer has a coil resistance of Rgalv = 13.9 ?. It is to be made into a voltmeter with a full-scale voltage equal to V = 325.0 V. If the galvanometer deflects full scale for a current of Igalv = 245.5 mA, what size additional resistor should be used?
A galvanometer has a coil resistance of ?galv=27.4 Ω . It is to be made into a voltmeter with a full‑scale voltage equal to ?=225.0 V.

The coil of wire in a galvanometer has a resistance of RC = 75.0 Ω. The galvanometer exhibits a full-scale deflection when the current through it is 0.200 mA. A resistor is connected in series with this combination so as to produce a voltmeter. The voltmeter is to have a full-scale deflection when it measures a potential difference of 14.0 V. What is the resistance of this resistor?
Moving a magnet in and out of a coil will make the needle on a galvanometer move to each side. a) explain what is happening in terms of magnetic induction. b) what would it take to induce an emf that stays positive, or that stays negative? is it possible? c) how can you get the largest possible deflection of the needle? explain what you do in terms of the magnetic field of the magnet, and the induced emf.
A galvanometer has a coil resistance of 20 Ω . A current of 200 μA deflects the needle through ten divisions at full scale. Part A What resistance is needed to convert the galvanometer to a full-scale 11 V voltmeter? the answer needs to be in kΩ
A galvanometer has a coil with a resistance of 24.0 ?, and a current of 180 ?A causes it to deflect full scale. If this galvanometer is to be used to construct an ammeter that can read up to 10.0 A, what shunt resistor in micro-ohms is required?
In the ballistic galvanometer the charge Q passes through the coil in a small fraction of the time required for the full swing of the coil. What basic mechanical property must the coil possess in order that the swing continue after the deflecting torque has vanished? This is the physics lab 2 question. Anyone please can help me? The lab was measurements of Capacitance!
