## Secondary Voltage Formula:

Secondary voltage is a fundamental concept in the realm of electrical engineering, particularly in the context of transformers and voltage conversion circuits.

This voltage is crucial in systems where voltage levels need adjustment for safe and efficient power distribution and utilization.

Secondary voltage refers to the voltage that results from the transformation process in a transformer or a similar device, where a primary voltage (V1) is converted based on the ratio of currents flowing through the device.

Secondary voltage, V2(V) in volts equals the product of primary voltage, V1(V) in volts and primary current, I1(A) in amperes divided by the secondary current, I2(A) in amperes.

Secondary voltage, V2(V) = V1(V) *  I1(A) / I2(A)

V2(V) = secondary voltage in volts, V.

V1(V) = primary voltage in volts, V.

I1(A) = primary current in amperes, A.

I2(A) = secondary current in amperes, A.

### Secondary Voltage Calculation:

1. Calculate the secondary voltage for a transformer where the primary voltage is 120 volts, primary current is 10 amperes, and the secondary current is 20 amperes:

Given: V1(V) = 120V, I1(A) = 10A, I2(A) = 20A.

Secondary voltage, V2(V) = V1(V) *  I1(A) / I2(A)

V2(V) = 120 * 10 / 20

V2(V) = 120 / 20

V2(V) = 60V.

1. Suppose a transformer’s primary voltage is 230 volts and the primary current is 5 amperes. If the secondary voltage is 460V, calculate the secondary current:

Given: V1(V) = 230V, I1(A) = 5A, V2(V) = 460V.

Secondary voltage, V2(V) = V1(V) *  I1(A) / I2(A)

I2(A) = V1(V) *  I1(A) / V2(V)

I2(A) = 230 * 5 / 460

I2(A) = 1150 / 460

I2(A) = 2.5A.

### Applications and Considerations:
