Electrocution Safety#

A person with body resistance between their hands of 11.75 \(\rm\ k \Omega\) accidentally grasps the terminals of a 20.5 \(\rm\ kV\) power supply.

(Do NOT do this!)

Part 1#

If the internal resistance of the power supply is 2400 \(\rm\ \Omega\), 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 0.6 \(\rm\ mA\) or less?

Answer Section#

Please enter a numeric value.
