FAQ

What is Value of Thevenin Resistance?
The Value of Thevenin Resistance formula is used to calculate the total resistance effective in an unbalanced Wheatstone bridge in which Rg is not zero and is represented as Rth=((R1*R3)/(R1+R3))+((R2*Rx)/(R2+Rx)) or Resistance (Thevenin)=((Resistance 1*Resistance 3)/(Resistance 1+Resistance 3))+((Resistance 2*Unknown Resistance)/(Resistance 2+Unknown Resistance)). Resistance 1 is the value of resistance connected in arm AD (ABCD is labelled clockwise, with A being labelled at the top), Resistance 3 is the value of resistance connected in arm CD (ABCD is labelled clockwise, with A being labelled at the top), Resistance 2 is the value of resistance connected in arm AB (ABCD is labelled clockwise, with A being labelled at the top) and Unknown Resistance is the value of resistance connected in arm BC (ABCD is labelled clockwise, with A being labelled at the top).
How to calculate Value of Thevenin Resistance?
The Value of Thevenin Resistance formula is used to calculate the total resistance effective in an unbalanced Wheatstone bridge in which Rg is not zero is calculated using Resistance (Thevenin)=((Resistance 1*Resistance 3)/(Resistance 1+Resistance 3))+((Resistance 2*Unknown Resistance)/(Resistance 2+Unknown Resistance)). To calculate Value of Thevenin Resistance, you need Resistance 1 (R1), Resistance 3 (R3), Resistance 2 (R2) and Unknown Resistance (Rx). With our tool, you need to enter the respective value for Resistance 1, Resistance 3, Resistance 2 and Unknown Resistance and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
