Question 9

An electrical device requires an alternating voltage of 6.0 V to operate normally. The mains supply voltage is 240 V. Which transformer provides the correct output voltage to enable the device to operate normally when connected to the mains supply?

A

Number of turns on primary coil = 600600600, number of turns on secondary coil = 24 00024\,00024000

B

Number of turns on primary coil = 600600600, number of turns on secondary coil = 2 4002\,4002400

C

Number of turns on primary coil = 24 00024\,00024000, number of turns on secondary coil = 600600600

D

Number of turns on primary coil = 2 4002\,4002400, number of turns on secondary coil = 600600600
