When testing a fuse with an Ohmmeter, a good fuse should have….
- A.
High resistance
- B.
Low resistance
- C.
Fuses can’t be tested with an ohmmeter
- D.
Ohmmeters do not measure resistance
Correct Answer
B. Low resistanceExplanation
Low resistance means current can flow, until too much shows up, then the trouble starts....Rate this question:

A relay uses _________ to _____________?
- A.
Low voltage; activate a high voltage circuit
- B.
Low resistance; activate a high resistance circuit
- C.
High current; activate a low current circuit
- D.
Low current; activate a high current circuit
Correct Answer
D. Low current; activate a high current circuitExplanation
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.Rate this question:

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)
- A.
16 A
- B.
12 A
- C.
24 A
- D.
8 A
Correct Answer
C. 24 AExplanation
A = V/Ohms.
A = 12V/3 Ohms
A = 4
4A x 4 lights = 16A
16A x 1.5 (surge factor) = 24ARate this question:

For a higher current circuit you would want what sort of gauge wire?
- A.
Smaller gauge number
- B.
Larger gauge number
- C.
Doesn’t matter, because current isn’t affected by wire gauge
- D.
14 gauge wire is the best for high current circuits
Correct Answer
A. Smaller gauge numberExplanation
In another example of technical backwardness, smaller gauge numbers means larger wire, which means more current can flow through it.Rate this question:

In wiring diagrams and electrical schematic drawings, where is the positive side drawn?
- A.
Top
- B.
Bottom
- C.
Left hand side
- D.
Right hand side
Correct Answer
A. TopExplanation
As far as wiring diagrams are concerned, electricity flows (mostly) from top to bottom.Rate this question:
