call the fire department
use an abc fire extinguisher
switch the main breaker off
pour water on the flames

the electric company bills customers based on the____used. *
voltage
energy
current
power

Explanation:

• First question: Water is a conductor of electricity. Pouring water on an electrical fire can cause electrocution and spread the fire. Calling the fire department, using an ABC fire extinguisher (which is suitable for electrical fires as it can insulate and smother the fire), and switching the main breaker off (to cut off the power source) are all correct actions.
• Second question: Electric companies bill customers based on the amount of energy consumed. Voltage is the potential difference, current is the flow of electric charge, and power is the rate of energy transfer. But the billing is based on the total energy (measured in kilowatt - hours, for example) used over a period.

Answer:

• First question: Pour water on the flames.
• Second question: Energy.
