Question

Число витков в первичной обмотке трансформатора в 4 раза меньше числа витков во вторичной обмотке трансформатора. На первичную обмотку подали напряжение U. Чему равно напряжение на вторичной обмотке трансформатора?

Answer 1

Ответ:

Напряжение будет 4*U (В 4 раза больше)

Answer 2

Calculating Voltage in the Secondary Coil of a Transformer

When the number of turns in the primary coil of a transformer is four times less than the number of turns in the secondary coil, and a voltage U is applied to the primary coil, the voltage in the secondary coil can be calculated using the transformer equation:

U1 / U2 = N1 / N2

Where: - U1 = voltage in the primary coil - U2 = voltage in the secondary coil - N1 = number of turns in the primary coil - N2 = number of turns in the secondary coil

Using the given information, we can calculate the voltage in the secondary coil.

The voltage in the secondary coil (U2) can be calculated using the formula:

U2 = (N2 / N1) * U1

Where: - N1 = number of turns in the primary coil - N2 = number of turns in the secondary coil - U1 = voltage in the primary coil

Substituting the given values: - N1 = number of turns in the primary coil - N2 = 4 * N1 (as the number of turns in the primary coil is four times less than the number of turns in the secondary coil) - U1 = voltage applied to the primary coil

We can calculate the voltage in the secondary coil using the above formula.

U2 = (4 * N1 / N1) * U1

This simplifies to: U2 = 4 * U1

Therefore, the voltage in the secondary coil of the transformer is four times the voltage applied to the primary coil.
