Electrocution Safety#

A person with body resistance between their hands of 10.25 $$\rm\ k \Omega$$ accidentally grasps the terminals of a 20.0 $$\rm\ kV$$ power supply.

(Do NOT do this!)

Part 1#

If the internal resistance of the power supply is 2000 $$\rm\ \Omega$$, what is the current through their body?

Part 2#

What is the power dissipated in their body?

If the power supply is to be made safe by increasing its internal resistance, what should the internal resistance be for the maximum current in this situation to be 1.0 $$\rm\ mA$$ or less?
