Electrical safety and shock question

Briefly, discuss the aspects of electrical safety and shock.

Electrical Problem

A person has a 72 V battery along with 6, 9, and 18 ohm resistors. They are first wired in series, then is parallel. First, sketch each circuit. Then, find the current in each resistor as well as the voltage across each resistor for each resistor, for each circuit.
