Final answer:
False. The number of turns in the primary and secondary coils of a transformer depends on the desired voltage ratio.
Step-by-step explanation:
False. In a transformer, the primary coil does not always have more turns than the secondary coil. The number of turns in the primary and secondary coils depends on the desired voltage ratio of the transformer.
For a step-up transformer, which increases voltage and decreases current, the ratio of secondary to primary turns is greater than one. For a step-down transformer, which decreases voltage and increases current, the ratio of secondary to primary turns is less than one.
Therefore, the statement that the primary coil always has more turns than the secondary coil is false.
