- Mains AC: non-invasive | OpenEnergyMonitor
This method of measuring mains AC electrical energy use is quite nice, it doesn't require any breaking of the mains wire, which makes it nice and safe, you just clip-on to the wire a sensor called a current transformer (CT) that measures the current flowing through either the live or neutral mains wire. It does this by measuring the magnetic field that surrounds the wire, created by the current. The simplicity of just clipping on the sensor means that it can be used to measure the electrical energy used by the whole house. It a method used by many commercial devices that you can buy.

- National High Magnetic Field Laboratory - Current Flow Tutorial
Current Flow This tutorial illustrates how the flow of water through a system of pipes can be used to understand the flow of current through an electric circuit. Here blue particles represent the flow of water, moving as electrons do through a circuit to create electricity. The rate of water flow, defined as the volume of the fluid moving past a certain point in a fixed amount of time, is comparable to the rate of charge passing a point in a circuit (electric current), which is measured in amperes (coulombs/second).
