About This Quiz

Explore key concepts in automotive electrical systems with 'Auto 13 - Electrical part II'. This quiz assesses understanding of electrical components like fuses, relays, and wiring, emphasizing practical applications such as circuit protection and schematic interpretation.

2.

In wiring diagrams and electrical schematic drawings, where is the positive side drawn?
- Top
- Bottom
- Left hand side
- Right hand side
Correct Answer

A. Top

Explanation

As far as wiring diagrams are concerned, electricity flows (mostly) from top to bottom.

3.

For a higher current circuit you would want what sort of gauge wire?
- Smaller gauge number
- Larger gauge number
- Doesn’t matter, because current isn’t affected by wire gauge
- 14 gauge wire is the best for high current circuits
Correct Answer

A. Smaller gauge number

Explanation

In another example of technical backwardness, smaller gauge numbers means larger wire, which means more current can flow through it.

4.

A relay uses _________ to _____________?
- Low voltage; activate a high voltage circuit
- Low resistance; activate a high resistance circuit
- High current; activate a low current circuit
- Low current; activate a high current circuit
Correct Answer

A. Low current; activate a high current circuit

Explanation

Basically, a small flashlight's worth of current can switch a high beam light level of current. It's a convenient way of controlling circuits.

5.

You’re adding 4 bush lights at 3 ohms each. What rating of fuse should you use to protect the new circuit? (use a “surge factor” of 1.5)
- 16 A
- 12 A
- 24 A
- 8 A
Correct Answer

A. 24 A

Explanation

A = V/Ohms.
A = 12V/3 Ohms
A = 4
4A x 4 lights = 16A
16A x 1.5 (surge factor) = 24A
