Answer:
I = 8.3 Amp
potential drop = 83 V
Explanation:
Power = 100 KW
V = 12,000 V
R = 10 ohms
a)
Calculate current I in each wire:
P = I*V
I = P / V
I = 100 / 12 = 8.333 A
b)
Calculate potential drop in each wire:
V = I*R
V = (8.3) * (10)
V = 83 V

The options are:
A. You will be exposed to splashes of the material.
B. You will have to handle the material.
C. There are high atmospheric concentrations of the material.
D. None of the above.
Answer:
None of the above
Explanation:
Structural firefighting protective clothing can't give adequate protection when one is exposed to splashes of the material. Moreover, it can't help in a situation where one is required to handle the material or when there are high atmospheric concentrations of the material.
SFC may be used when the following conditions are met:
• Contact with splashes of extremely hazardous materials is unlikely.
• Total atmospheric concentrations do not contain high levels of chemicals toxic to the skin.
• There are no adverse effects from chemical exposure to small areas of unprotected skin.
• Live victims who are in need of rescue, such as those found in a terrorist attack.
