Here are over 300 vector-based .wmf files covering a variety of bits of electrical & electronic equipment and symbols. The zipped folder titles correspond to a number of areas in Physics. To get the graphics click on any link e.g. Equipment symbols :-

Once you have extracted the files you can then drag and drop the graphics into Word or PowerPoint. If you can’t see the graphics as wmf file thumbnails in Windows 7, install this plug-in http://code.google.com/p/emfplugin/. You’ll need to restart your computer for the plug-in to take effect.
Editing files with PowerPoint – If want to tweak the files you have loaded into a PowerPoint page right-click the mouse button over the image then I. You are then asked if you want to convert it to a Microsoft drawing object. Click Yes. You should then be able to pick up the constituent bits of the image. Please note that the text can be picked out as single letter images but cannot be edited as ASCII text.
Note also you may come across some objects which have no apparent function. Try Ctrl-C then Ctrl-V on an object to see what its copy looks like e.g. A colourless fill in the shape of the object. Try adding colour fills now via Home then Shape Fill/Effects.
You should also be able to import these files into the free vector program Inkscape.
