Question 1

Which type of fire extinguisher is appropriate for electrical fires?

Accepted Answer

CO2 or dry chemical (Class C)

Answer

Class C fire extinguishers (CO2 or dry chemical) are designed for electrical fires. Water-based extinguishers should never be used on electrical fires as water conducts electricity and can cause electrocution.

Question 2

Accepted Answer

Cooking food quickly in a small amount of fat over high heat

Answer

Sauteing is a cooking method that uses a small amount of fat (oil or butter) in a pan over relatively high heat. The food is cooked quickly and kept moving in the pan to ensure even cooking.

Question 4

Which of the following is a characteristic of a series circuit?

Accepted Answer

The current is the same through all components

Answer

In a series circuit, there is only one path for current to flow, so the same current passes through all components. If one component fails, the entire circuit is broken.

Question 5

What is the correct unit of measurement for electrical resistance?

Accepted Answer

Ohm

Answer

Electrical resistance is measured in ohms (Ω), named after German physicist Georg Simon Ohm. Amperes measure current, volts measure voltage, and watts measure power.
