Understanding Electric Plugs, Voltage, and Frequency

Introduction

This guide explains the different electric plugs, voltage, and frequency standards around the world.

Electric Plugs

  • Different countries use different types of electric plugs.
  • Common plug types include A, B, C, D, E, F, G, H, I, J, K, L, M, N, and O.
  • A travel adapter is needed to use your devices in countries with different plug types.

Voltage

  • Voltage is the electrical potential difference between two points in an electrical circuit.
  • Different countries use different voltage standards.
  • Common voltage standards include 100V, 120V, 220V, 230V, and 240V.
  • A voltage converter is needed to use your devices in countries with different voltage standards.

Frequency

  • Frequency is the number of cycles per second of an alternating current (AC) electrical power supply.
  • Different countries use different frequency standards.
  • Common frequency standards include 50 Hz and 60 Hz.
  • Most modern electronic devices are designed to work with both 50 Hz and 60 Hz.
