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 (Rg), Ballast Resistance (Rb) and Input Supply Voltage (vi).
The formula to calculate ballast circuit output voltage under no load condition:
vo = (Rg / Rg + Rb)vi
Where:
vo = Ballast Circuit Output Voltage
Rg = Resistance of the Unstrained gauge
Rb = Ballast Resistance
vi = 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;
Rg = Resistance of the Unstrained gauge = 12
Rb = Ballast Resistance = 10
vi = Input Supply Voltage = 8
vo = (Rg / Rg + Rb)vi
That is, vo = (12 / 12 + 10) x 8
vo = (12 / 22) x 8
So, vo = 0.54 x 8
vo = 4.36
Therefore, the ballast circuit output voltage is 4.36 V.
