What exactly happens to an electronic device when hit by an EMP? Can it be turned on again?
In: 25
EMP sets up a voltage difference between the different sides of the device. If the voltage difference is too high, it blows out various components. (Field effect transistors are very sensitive to over voltages.) If components blow, it won’t work until repaired or replaced.
You can protect stuff by wrapping it in aluminum foil and leaning it against a metal water pipe.
