A method to evaluate the plasma resistance of the Extrap-T1 pinch is described. The method is based on a model for the secondary side of the Ohmic heating transformer circuit. Extrap-T1 plasma resistance data are presented. An experimental test of the model shows that the method could be used with good accuracy in the normal region of the machine. The plasma resistance is found to attain its minimum value close to the time of the plasma current maximum.
