Inform me, what is the approximate resistance of the human entire body, from a single fingertip to the other? Let’s think the skin is just not moist, but not dry. Now, just how much current will it get to disrupt the electrical action of the heart?
This could frequently be done Along with the visual inspection stage we talked about before, which includes noticing evident signs of Bodily hurt, which include loose or disconnected wires, blown capacitors which may be regarded by their bulging or leaking tops, bent or damaged pins to the connectors, cracked or discolored components, or signs of overheating.
Its employing a very strange 5 pin regulator around the secondary side, among the circuit protectors had failed but changing that didn’t help.
