What makes a shock dangerous?

A common myth is that "Voltage kills." In reality, the danger of an electric shock is determined entirely by the Current (Amps). However, because of Ohm's Law ($I = V/R$), voltage and resistance directly control how much current flows.

  • Voltage (V) is the push: Think of it like water pressure. A 10,000V static shock from a doorknob has massive pressure, but almost no volume (current), so it just stings.
  • Resistance ($\Omega$) is the friction: The human body has high resistance when dry (around 100,000 $\Omega$), but extremely low resistance when wet (as low as 1,000 $\Omega$).
  • Current (A) is the actual flow: This is the volume of electrons moving through the material. In our simulator, the bulb has a maximum capacity of 1.0 Amp. If the push (Voltage) gets too high while the friction (Resistance) is too low, the resulting current overwhelms the wire, causing it to pop!
