A current transformer has two turns on the primary winding and a secondary winding of 260 turns.
The secondary winding is connected to an ammeter with a resistance of 0.2.The resistance of the secondary winding is 0.3. If the current in the primary winding is 650A.
Verify
(a) the reading on the ammeter,
(b) the potential difference across the ammeter, and
(c) the total load in VA on the secondary.
The mass of 1 mole of electrons is: (1) 9.1x 10 -28 g (2) 1.008mg (3) 0.55mg (4) 9.1x 10 -27 g Ans: (3)0.55mg
