Neon signs require about 12,000 volts to operate. If the circuit uses a 120-volt power source, the ratio of primary to secondary turns on the transformer should be
A)1 primary to 100 secondary.
B)100 primary to 1 secondary.
C)neither of these

Question

Quizplus · Accepted Answer

To step up the voltage from 120 volts to 12,000 volts, the transformer needs a turns ratio where the secondary coil has more turns than the primary. The correct ratio is 1 primary to 100 secondary, as this increases the voltage by a factor of 100 (120V * 100 = 12,000V).
