Question 1

Using Ohm's law, what is the current through a circuit with 12 volts and 4 ohms of resistance?

Accepted Answer

3 amps

Answer

Current equals voltage divided by resistance, so 12 ÷ 4 = 3 amps.

Question 2

A lever has its fulcrum closer to the load than to the effort. This arrangement primarily provides:

Accepted Answer

Increased mechanical advantage to lift heavy loads

Answer

Placing the fulcrum near the load gives a longer effort arm, increasing force to lift heavy loads.

Question 3

A graph shows temperature flattening into a horizontal line over time. What does the horizontal portion indicate?

Accepted Answer

Temperature is holding steady

Answer

A horizontal line means the value is not changing, so temperature is steady.

Question 4

A technician must follow a written work order that lists steps in numbered sequence. Why is following the exact order important?

Accepted Answer

Steps may depend on prior steps for safety and correctness

Answer

Numbered steps often build on each other, so skipping order can cause errors or hazards.

Question 5

Three resistors of 6 ohms each are connected in parallel. What is the total resistance?

Accepted Answer

2 ohms

Answer

Equal parallel resistors give total resistance of one resistor divided by the count: 6 ÷ 3 = 2 ohms.
