Most calculators operate on 6.0 V. If, instead of using batteries, you obtain 6.0 V from a transformer plugged into 110-V house wiring, what must the ratio of the primary to the secondary turns be in the transformer? (Ignore any changes in voltage due to rectification.)

1/0.0545

Explanation:

The transformer have a ratio of the primary turns to the secondary turns equivalent to the ratio of the voltage it is changing. If we have 6.0 V in the secondary (output), and 110 V in the primary (input) the ratio of the voltage is 6/110 = 0.0545, so the ratio between turns in the transformer is 1/0.0545 (for each turn in the primary, the transformer has 0.0545 turns in secondary)
