A transformer has 1000 turns in its secondary coil and 10 turns on its primary coil. An alternating current of 2.5A flows in the primary circuit when it is connected to a 12V a.c. supply.
(i) State the type of transformer.
(ii) Calculate the power input to the transformer.
(iii) Calculate the e.m.f. across the secondary coil.
(iv) Determine the maximum current that could flow in a circuit connected to the secondary coil if the transformer is 80% efficient. (Use the e.m.f in secondary as calculated in (iii) above).
