Question

Трансформатор понижает напряжение в 5 раз.Определите число витков в первичной катушке трансформатора,если вторичная катушка содержит 80 витков.

Answer 1

В пять раз больше, то есть 80*5=400

Answer 2

В пять раз больше, 5*80=400

Answer 3

Calculating the Number of Turns in the Primary Coil of a Transformer

To determine the number of turns in the primary coil of the transformer, given that the secondary coil contains 80 turns and the transformer reduces the voltage by a factor of 5, we can use the formula:

N1/N2 = V1/V2

Where: - N1 = number of turns in the primary coil - N2 = number of turns in the secondary coil - V1 = voltage in the primary coil - V2 = voltage in the secondary coil

Given that the transformer reduces the voltage by a factor of 5, we can express this as:

V2 = V1/5

Substituting this into the formula, we get:

N1/80 = V1/(V1/5)

Solving for N1:

N1 = 80 * 5

N1 = 400

Therefore, the number of turns in the primary coil of the transformer is 400.
