A Transformer Voltage Calculation Problem

Calculating Primary Voltage in a Transformer

In this scenario, the transformer has 192.6 turns on the primary side and 43.96 turns on the secondary side. The desired secondary voltage is 6.41 volts. To determine the voltage on the primary side, we can use the turns ratio formula and the voltage ratio in a transformer.

Given:
Number of turns on the primary (N1) = 192.6 turns
Number of turns on the secondary (N2) = 43.96 turns
Desired secondary voltage (V2) = 6.41 volts

Now, let's calculate the voltage on the primary side (V1):

Turns ratio = N1/N2 = 192.6/43.96
Voltage ratio = V1/V2 = Turns ratio
V1 = V2 * Turns ratio = 6.41 * 192.6/43.96

Performing the calculations:

V1 = 6.41 * 4.3832460733
V1 = 28.046 volts

Therefore, the voltage on the primary side of the transformer should be approximately 28.046 volts.
