Question 16

A transformer has 8000 turns on its primary coil and 400 turns on its secondary coil. Connected in this way, for what purpose could this transformer be used?

A

to convert the 11 000 V11\,000\text{ V}11000 V a.c. output of a power station to 220 000 V220\,000\text{ V}220000 V for long-distance power transmission

B

to convert the 220 000 V220\,000\text{ V}220000 V d.c. supply from a transmission line to 11 000 V11\,000\text{ V}11000 V for local distribution

C

to use a 12 V12\text{ V}12 V d.c. supply to operate a 240 V240\text{ V}240 V travel iron

D

to use a 240 V240\text{ V}240 V a.c. mains supply to operate a 12 V12\text{ V}12 V halogen bulb
