How Shock Is Measured:
I = V / R
To understand how electric shock can hurt you, let’s go back to the equation from Ohm’s Law
that had current on the left side, I equals V divided by R, or current equals voltage divided by
resistance.
Remember that voltage will often stay the same, so the current will depend on how much
resistance there is in the circuit.
If resistance is high, the shock will not be as bad as if the resistance is low. Higher resistance,
then, is better.
Resistance is reduced if you are wet or sweaty, or are not wearing the proper gloves or shoes,
making current (the part that kills you) much greater.
True of false?
When trying to stay safe around electrical hazards, keeping work areas dry and wearing proper
clothing can help keep your body’s resistance high and help keep you from getting shocked. ‐
