Deflection of Pointer Solution

STEP 0: Pre-Calculation Summary

Formula Used

Pointer Deflection = Galvanometer Deflection Angle*Controlling Torque
T_c = θ_g*T_c
This formula uses 3 Variables

Variables Used

Pointer Deflection - Pointer Deflection also known as needle deflection, refers to the movement of the pointer or needle in a measuring instrument such as a galvanometer.
Galvanometer Deflection Angle - (Measured in Radian) - Galvanometer Deflection Angle refers to the amount the needle of the galvanometer moves from its resting position when a current flows through it.
Controlling Torque - Controlling Torque in a galvanometer is the rotational force that moves the pointer or needle in response to the current passing through the instrument.

STEP 1: Convert Input(s) to Base Unit

Galvanometer Deflection Angle: 31.99 Radian --> 31.99 Radian No Conversion Required
Controlling Torque: 34 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

T_c = θ_g*T_c --> 31.99*34

Evaluating ... ...

Instantaneous Deflecting Torque

Go Torque (inst) = Resistance*Spring Constant*(((Current 1)^2)-((Current 2)^2))

Average Current through Galvanometer

Go Total Current = (2*Number of Turns*Magnetic Flux)/(Time*Resistance)

Voltage Sensitivity of Galvanometer

Go Voltage Sensitivity of Galvanometer = (Deflection Angle*(180/pi))/Potential Difference

Deflection in Galvanometer

Go Deflection Angle = (Potential Difference*Voltage Sensitivity of Galvanometer)*(pi/180)

EMF across Galvanometer

Go EMF = Resistance*(((Current 1)^2)-((Current 2)^2))

Angle of Deflection of Pointer

Go Galvanometer Deflection Angle = Pointer Deflection/Controlling Torque

Deflection of Pointer

Go Pointer Deflection = Galvanometer Deflection Angle*Controlling Torque

Naturally linkage Sensitivity

Go Natural Linkage Sensitivity = Flux Linkage Sensitivity/Resistance

Throw of Galvanometer

Go Throw of Galvanometer = Ballistic Sensitivity*Flux Charge

Constant of Galvanometer

Go Galvanometer Constant = Charge/Throw of Galvanometer

Ballistic Sensitivity

Go Ballistic Sensitivity = Throw of Galvanometer/Charge

Deflection of Pointer Formula

Pointer Deflection = Galvanometer Deflection Angle*Controlling Torque
T_c = θ_g*T_c

What is meant by damping torque?

Damping torque or damping forces is the speed deviation of electromechanical torque deviations of a machine while the angle deviation is called synchronizing torque. If the damping force is too large, then the pointer will come to rest slowly and this is called over-damping.

How to Calculate Deflection of Pointer?

Deflection of Pointer calculator uses Pointer Deflection = Galvanometer Deflection Angle*Controlling Torque to calculate the Pointer Deflection, The Deflection of Pointer formula is defined as on either side of the zero marks. A galvanometer is an instrument that is used for measuring a small electric current or a function of the current by deflection of a moving coil. While in ammeter and voltmeter, the gradation starts from the left side. Pointer Deflection is denoted by T_c symbol.
