Question

Трансформатор включен в сеть с напряжением 200В. Каково будет напряжение на вторичной обмотке, если в первичной обмотке 1000 витков, а во вторичной 200 витков?

Answer 1

U1/U2=n1/n2. U2=U1*n2/n1=200*200/1000=40 В.
Во вторичной витков меньше в 1000/200=5 раз, значит и напряжение будет в 5 раз меньше. 200/5=40 В. Ответ: 40 В.

Answer 2

Calculating the Voltage on the Secondary Coil of a Transformer

When a transformer is connected to a network with a voltage of 200V and has 1000 turns in the primary coil and 200 turns in the secondary coil, the voltage on the secondary coil can be calculated using the formula:

V2 = (N2 / N1) * V1

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

Using the given values: - N1 = 1000 turns - N2 = 200 turns - V1 = 200V

We can calculate the voltage on the secondary coil using the formula:

V2 = (200 / 1000) * 200

V2 = 0.2 * 200

V2 = 40V

Therefore, the voltage on the secondary coil will be 40V when the transformer is connected to a network with a voltage of 200V.

Conclusion

The voltage on the secondary coil of the transformer will be 40V when the primary coil has 1000 turns and the secondary coil has 200 turns, and the transformer is connected to a network with a voltage of 200V.
