Excellent write-up.
Maybe you could have added that volts x amperes is power, which is energy per unit time. So a high value of volts x amperes (watts or kilowatts) hitting a person implies that person getting zapped by a large amount of energy in an instant. (I am ignoring nuances of DC/AC current, the basic point still holds.)
We should start talking about getting hit by so many kilowatts of electrical power!
