=== Powered components === Touching a component can potentially add you to a circuit. Depending on what type of circuit this is this may do nothing, it may damage the component, or it may damage you. There are two particular categories of circuits you should watch out for: Low voltage and high voltage. The human body does not conduct much electricity at low voltage (I'll use 12 volts as my conservative definition here) so it's unlikely you'll damage yourself by touching a component. It is possible to damage components by unintentional paths between components. There main technique to avoid this is to touch only the ground parts of the circuit such as metal USB or Ethernet shields. High voltage is a different story (I'll define it as over 50 volts here) as your body may conduct enough electricity to shock you. Do not touch high voltage components. If you're unsure, don't touch the component at all. It will not be an enjoyable experience and it will accomplish nothing.
