Average Current through Galvanometer Solution

STEP 0: Pre-Calculation Summary

Formula Used

Total Current = (2*Number of Turns*Magnetic Flux)/(Time*Resistance)
I = (2*N*Φ)/(t*R)
This formula uses 5 Variables

Variables Used

Total Current - (Measured in Ampere) - Total Current refers to the sum of all currents passing through the galvanometer's circuit.
Number of Turns - Number of Turns refers to the number of wire turns in the coil of the galvanometer. This coil is typically made of a conducting wire wound around a core.
Magnetic Flux - (Measured in Weber) - Magnetic flux is a measure of the total magnetic field passing through a given area .It is generated when an electric current flows through a coil or conductor.
Time - (Measured in Second) - Time is the time required to reverse the current.
Resistance - (Measured in Ohm) - Resistance refers to the electrical resistance of the coil inside the galvanometer. This resistance is typically measured in ohms (Ω).

STEP 1: Convert Input(s) to Base Unit

Number of Turns: 100 --> No Conversion Required
Magnetic Flux: 2.6 Weber --> 2.6 Weber No Conversion Required

How is current set up in the coil?

The search coil, which is wound on a ring specimen, is connected to a ballistic galvanometer. The magnetising winding carries the current, which provides the flux o be measured. The current is then reversed by a reversing switch. The flux linkage associated with the search coil also changes, inducing EMF. The EMF drives the current through the galvanometer causing deflection.

How to Calculate Average Current through Galvanometer?

Average Current through Galvanometer calculator uses Total Current = (2*Number of Turns*Magnetic Flux)/(Time*Resistance) to calculate the Total Current, The Average Current through Galvanometer formula is directly dependent on the flux produced in the search coil but is inversely proportional to the time taken to reverse the direction of the said current. Total Current is denoted by I symbol.

How to calculate Average Current through Galvanometer using this online calculator? To use this online calculator for Average Current through Galvanometer, enter Number of Turns (N), Magnetic Flux (Φ), Time (t) & Resistance (R) and hit the calculate button. Here is how the Average Current through Galvanometer calculation can be explained with given input values -> 6.117647 = (2*100*2.6)/(5*17).
