Procedure to perform the simulation
To calibrate the Carey Fosters Bridge
Drag the ‘Resistor’ to the gap 2 and 3 of the Carey fosters bridge.
Drag ‘Fractional resistor' to gap 1.
Drag the Battery to space in between the two ‘Resistors’.
Drag the copper strip to gap 4.
Press the continue button, on the top.
Click and unmark the resistance which has to be introduced in ‘Resistor’.
Power On button to start and power off to stop the experiment.
Change the position of jockey to get balancing length l1’.
Reverse connection button to interchange copper strip with fractional resistor.
Move jockey to get balancing length l2’.
Resistance per cm of bridge wire is found using equation
