Hertz to Ampere Calculator

What is the Hertz to Ampere Calculator?

This calculator helps you convert frequency (hertz) to electrical current (amperes) using the relationship between frequency, voltage, and inductance in AC circuits.

Understanding the Calculation

Basic Formula

The formula to calculate current from frequency is:

Current (A) = Voltage / (2π × Inductance × Frequency)

Example Calculations

• If frequency is 50Hz, voltage is 220V, and inductance is 0.5H:
  A = 220 / (2π × 0.5 × 50) ≈ 1.40 A
• If frequency is 60Hz, voltage is 110V, and inductance is 0.1H:
  A = 110 / (2π × 0.1 × 60) ≈ 2.92 A

Common Unit Relationships

• 1 kilohertz (kHz) = 1000 Hz
• 1 megahertz (MHz) = 1,000,000 Hz
• 1 milliampere (mA) = 0.001 A
