Switch on the mains first. Note down the readings by connecting voltmeter across the coil terminals,one pair at a time: a1a2,a3a4,a1a3,a2a4. Note down the readings by connecting voltmeter across the coil terminals,one pair at a time: a1a2,a3a4,a1a4,b2b4,b3b4,b1b4. Note down the readings by connecting voltmeter across any pair of coil terminals from amongst: a3,a4,b1,b2,b3,b4. Put on switch and observe what happens. A2A3 are connected measure voltage accross A1A4 Answer the follwing question Switch on the mains. Let us load the secondary side of the transformer with a load of 2A, and observe all the ammeter readings. Increase load to 5A and observe. Increase load to 10A and observe. Increase load to 12A and observe. With a1a3 shorted measure voltage for a1b1.
