Electrocution Safety#

A person with body resistance between their hands of 11.00 $\mathrm{k}\mathrm{\Omega }$ accidentally grasps the terminals of a 20.5 $\mathrm{k}\mathrm{V}$ power supply.

(Do NOT do this!)

Part 1#

If the internal resistance of the power supply is 2050 $\mathrm{\Omega }$, what is the current through their body?

Answer Section#

Please enter a numeric value.

Part 2#

What is the power dissipated in their body?

Answer Section#

Please enter a numeric value.

Part 3#

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 $\mathrm{m}\mathrm{A}$ or less?

Answer Section#

Please enter a numeric value.
