Power conversion refers to the process of converting power from one form to another, typically involving the transformation of electrical energy into another usable form or vice versa. This conversion may involve changing the voltage, current, frequency, or phase of electrical power to suit different applications or devices. Power conversion can occur in various contexts, including electrical systems, mechanical systems, and renewable energy systems, among others. The goal of power conversion is to efficiently transfer and utilize energy in different forms to meet specific needs or requirements.

The formula for power conversion depends on the specific type of conversion being performed. 

Here are some common formulas for power conversion:

1. Electrical Power Conversion:

• The electrical power (P) in watts (W) is equal to the product of the voltage (V) in volts (V) and the current (I) in amperes (A)
• The electrical power (P) in watts (W) is equal to the square of the voltage (V) in volts (V) divided by the resistance (R) in ohms (Ω)
•  The electrical power (P) in watts (W) is equal to the square of the current (I) in amperes (A) multiplied by the resistance (R) in ohms (Ω).

2. Mechanical Power Conversion:

• The mechanical power (P) in watts (W) is equal to the work done (W) in joules (J) divided by the time (t) in seconds (s).

3. Other Forms of Power Conversion:

•  The power (P) in watts (W) is equal to the energy (E) in joules (J) divided by the time (t) in seconds (s).

These are just a few examples of power conversion formulas. The specific formula to use depends on the type of energy being converted and the particular circumstances of the conversion process.
