Enter the power, voltage, and phase angle into the calculator to determine the current in an AC system.

Hz To Amps Formula

The following formula is used to calculate the current in an AC system. 

I = P / (V * sqrt(2) * cos(θ))

Variables:

  • I is the current in amperes (Amps)
  • P is the power in watts (W)
  • V is the voltage in volts (V) sqrt(2) is the square root of 2, a constant in AC power calculations
  • cos(θ) is the cosine of the phase angle (θ), which represents the phase difference between the voltage and the current in an AC system

To calculate the current in an AC system, divide the power by the product of the voltage, the square root of 2, and the cosine of the phase angle. Note that the frequency (Hz) does not directly factor into this calculation, but it can affect the phase angle and the power factor in more complex AC systems.

What is Hz To Amps?

Hz (Hertz) and Amps (Amperes) are two different units used in electrical systems. Hz is a unit of frequency that measures the number of cycles per second of a periodic phenomenon, particularly in alternating current (AC) electricity. On the other hand, Amps is a unit of electric current, representing the flow of electric charge. Therefore, “Hz to Amps” does not represent a direct conversion as they measure different aspects of electricity. However, they can be related in calculations involving power in AC systems, where the power (in watts), voltage (in volts), current (in amps), and frequency (in Hz) are interconnected.

How to Calculate Hz To Amps?

The following steps outline how to calculate the Hz To Amps using the formula: I = P / (V * sqrt(2) * cos(θ))

  1. First, determine the power in watts (P).
  2. Next, determine the voltage in volts (V).
  3. Next, determine the square root of 2 (sqrt(2)).
  4. Next, determine the cosine of the phase angle (cos(θ)).
  5. Finally, calculate the current in amperes (I) using the formula I = P / (V * sqrt(2) * cos(θ)).
  6. After inserting the variables and calculating the result, check your answer with a calculator.

Example Problem:

Use the following variables as an example problem to test your knowledge:

Power (P) = 500 watts

Voltage (V) = 120 volts

Square root of 2 (sqrt(2)) = 1.414

Cosine of the phase angle (cos(θ)) = 0.866
