So say if you're in a vacuum, breathing via a space suit (so you're not grounded and are surrounded by perfect insulation) and you touch something with very high voltage relative to you, would you completely safe no matter how high the voltage is? Note I've made the setting a vacuum deliberately so issues like conducting via air to the ground (eg lightning) can be ignored, and so the charges you gain don't leave you. In other words, is current only harmful when it can flow through and out of you? Are you safe when you receive an extremely high amount of charge if the charge can't flow out of you? Similarly when static electricity damages the inside components of a computer, does there need to be a conducting path between the computer and the ground for the computer to be damaged? Or does simply discharging charges to computer components damage them even when the charges stay inside it and have no way of flowing out?
