Offline Procedure
Connect the circuits as shown in figure 1.Increase the supply voltage (V1) in steps and note down the readings in all the ammeters. (I1`,I`2,I`3). (at least six set of readings).Connect the circuit as shown in figure 2.Increase the supply current (I) in steps and note down the readings in all the ammeters. (I1``,I``2,I``3). (at least six set of readings)
Connect adjust the voltages V1 and V2 in steps as in step 2 and step 4. (I1,I2,I3).
