Question

3. Обмотки котушок понижувального трансформатора містять 150 і 60 витків проводу відповідно. Яку напругу знімають із вторинної обмотки, якщо трансформатор увімкнений у мережу з напругою 220 В?

Answer 1

Відповідь:

U2=88V

Пояснення:

U1/U2=ω1/ω2⇒U1*ω2/ω1⇒220*60/150=88

Answer 2

Calculating Voltage Output from Secondary Coil of Transformer

The voltage output from the secondary coil of a transformer can be calculated using the formula:

V_secondary = V_primary * (N_secondary / N_primary)

Where: - V_secondary = Voltage output from the secondary coil - V_primary = Voltage input to the primary coil - N_secondary = Number of turns in the secondary coil - N_primary = Number of turns in the primary coil

Given: - Number of turns in the primary coil (N_primary) = 150 - Number of turns in the secondary coil (N_secondary) = 60 - Voltage input to the primary coil (V_primary) = 220 V

Using the formula, we can calculate the voltage output from the secondary coil:

V_secondary = 220 * (60 / 150)

V_secondary = 88 V

Therefore, the voltage taken from the secondary coil when the transformer is connected to a 220 V power supply is 88 V.
