    Hi Ben.

    Electric fields generated around household appliances are normally very
    weak. An exception is a CRT based TV that has such a strong field
    around it that you can easily get shocks by just tuching the screen.

    There are tools that do mesure the electric field around a charged object.
    They are called: Electrometer or Electric field meter.

    Most electrometers are based on a component called FET (Field effect
    transistor).

    Here is a small charge detector project for you with plenty of information
    about
    how it works:

    There are also a lots of other interesting articles to read about
    electricity here:
