How to Calculate and Solve for Ballast Circuit Output Voltage under No Load Condition | Electrical Strain Gauges

Last Updated on April 24, 2024

The image above represents ballast circuit output voltage under no load condition. To calculate ballast circuit output voltage under no load condition, three essential parameters are needed and these parameters are the Resistance of the Unstrained Gauge (R_g), Ballast Resistance (R_b) and Input Supply Voltage (v_i).

The formula to calculate ballast circuit output voltage under no load condition:

v_o = (^R_g / _{Rg + Rb})v_i

Where:

v_o = Ballast Circuit Output Voltage
R_g = Resistance of the Unstrained gauge
R_b = Ballast Resistance
v_i = Input Supply Voltage

Let’s solve an example;
Find the ballast circuit output voltage when the resistance of the unstrained guage is 12, the ballast resistance is 10 and the input supply voltage is 8.

This implies that;

R_g = Resistance of the Unstrained gauge = 12
R_b = Ballast Resistance = 10
v_i = Input Supply Voltage = 8

v_o = (^R_g / _{Rg + Rb})v_i
That is, v_o = (¹² / _{12 + 10}) x 8
v_o = (¹² / ₂₂) x 8
So, v_o = 0.54 x 8
v_o = 4.36

Therefore, the ballast circuit output voltage is 4.36 V.
