Question

In a transformer, there is a primary voltage of 130V and a secondary voltage of 50V. If there are 5 turns in the secondary coils, how many turns are in the primary coils?

Answer 1

To find the number of turns in the primary coils, you can use the formula for the turns ratio of a transformer:

Turns ratio = (Number of turns in primary coils) / (Number of turns in secondary coils)

Given that the secondary voltage is 50V and the primary voltage is 130V, we can use the turns ratio formula to calculate the number of turns in the primary coils.

Turns ratio = (Primary voltage) / (Secondary voltage)

Turns ratio = 130V / 50V

Turns ratio = 2.6

Since the turns ratio is equal to the ratio of the number of turns, we can calculate the number of turns in the primary coils by multiplying the turns ratio by the number of turns in the secondary coils.

Number of turns in primary coils = (Turns ratio) x (Number of turns in secondary coils)

Number of turns in primary coils = 2.6 x 5

Number of turns in primary coils = 13

Therefore, there are 13 turns in the primary coils.

Answer 2

To determine the number of turns in the primary coils, we can use the transformer turns ratio equation. The turns ratio is the ratio between the number of turns in the primary coil (Np) and the number of turns in the secondary coil (Ns). It can be calculated using the following formula:

Turns Ratio (TR) = Np / Ns

In this case, we have the secondary voltage (Vs) as 50V and the primary voltage (Vp) as 130V. The turns ratio can be expressed as:

TR = Vp / Vs

Substituting the given values,

TR = 130V / 50V

Now, the turns ratio is also equal to the ratio of the number of turns in the coils. So, we can rewrite the equation as:

TR = (Np / Ns)

Since we know the turns ratio (TR) and the number of turns in the secondary coil (Ns), we can rearrange the equation to solve for the number of turns in the primary coil (Np):

Np = TR * Ns

Plugging in the values we have:

Np = TR * 5

As we want to find the number of turns in the primary coil, we need to calculate the turns ratio and multiply it by the number of turns in the secondary coil.

Answer 3

The number of turns in the primary coils is 25. This is calculated by dividing the secondary voltage (50V) by the primary voltage (130V) and then multiplying the result by the number of turns in the secondary coils (5).
