To increase the amount of output voltage, it is common practice to increase the number of turns of wire for each loop. If a loop contains 20 turns of wire, the induced voltage will be 40 times greater than that for a single-loop conductor.

Question

Quizplus · Accepted Answer

Doubling the number of turns from 1 to 20 increases the induced voltage by a factor of 20, not 40. The induced voltage is directly proportional to the number of turns.
