Question

Первичная обмотка трансформатора содержит 100 витков, а вторичная 50 витков. какое напряжение будет на вторичной обмотке,если к первичной подключить батарейку с напряжением 3В?

Answer 1

Никакого напряжения не будет, так как трансформатор работает только на переменном токе за счёт взаимоиндукции, а батарейка даёт постоянное напряжение.

Answer 2

Calculation of Voltage on the Secondary Coil of a Transformer

To calculate the voltage on the secondary coil of a transformer, we need to consider the turns ratio between the primary and secondary coils. In this case, the primary coil has 100 turns, and the secondary coil has 50 turns.

The turns ratio (N1/N2) is given by the formula:

N1/N2 = V1/V2

Where: - N1 is the number of turns in the primary coil - N2 is the number of turns in the secondary coil - V1 is the voltage applied to the primary coil - V2 is the voltage across the secondary coil

In this scenario, a battery with a voltage of 3V is connected to the primary coil. We can use this information to calculate the voltage on the secondary coil.

Let's substitute the given values into the formula:

100/50 = 3/V2

To find V2, we can cross-multiply and solve for V2:

100V2 = 50 * 3

V2 = (50 * 3) / 100

V2 = 1.5V

Therefore, the voltage on the secondary coil will be 1.5V when a 3V battery is connected to the primary coil.

Please note that this calculation assumes an ideal transformer with no losses. In practice, there may be some losses due to factors such as resistance and magnetic leakage.
