How is it that doctors can use the electric paddles on patients with ear or body piercings in place? Won’t the electric shock burn the piercing sites around the metal?
In: Technology
High electrical currents are necessary to heat up metals, not voltage.
Defibrillators provide short bursts of high voltages with moderate current (less than 20 amps). Even if a metallic piercing happened to be in between the shock paddle and flesh, such current for such a short time is not likely to affect the metal.
