Below are sample questions representative of the exercises included on this worksheet and related 12.117 Circuit Diagrams, Meters, and Electrical Safety skill assessments:

Problem 1Difficulty: Mastery

The final schematic has a battery, fuse, switch, two lamp branches, and meters. The ammeter is drawn directly across the battery terminals while the voltmeter is across one lamp. What flaw must be fixed first?

AThe voltmeter across the lamp must be moved into series with the fuse.

BThe fuse should be placed in parallel with the ammeter so it can measure current.

CThe two lamp branches must be changed to one ideal wire to reduce resistance.

DThe ammeter across the battery creates a short path and must be moved into series with the current being measured.

Solution & Explanation:The most serious flaw is the ammeter placed across the source, because its low resistance can draw excessive current. The ammeter belongs in series with the branch or total current being measured.

Problem 2Difficulty: Mastery

Before building from a circuit diagram, which checklist best identifies a safe, functional design?

AShortest possible wire across the source, meters anywhere, and no load needed.

BVoltmeter in series, ammeter in parallel, and switch bypassing every load.

CClosed intended path, suitable load to limit current, protection in series, and correct meter placement.

DAll components connected to the same node so the diagram is compact.

Solution & Explanation:A safe functional circuit has an intended complete path through loads, avoids unintended shorts, includes appropriate protection, and places meters according to what they measure.

Problem 3Difficulty: Mastery

A 24 V battery is accidentally shorted by a wire with total resistance 0.12 ohm. What fault current is predicted before protection opens the circuit?

A2.9 A, because current equals resistance divided by voltage.

B200 A, which shows why overcurrent protection is essential.

C24 A, because the voltage number is the current number.

D0.005 A, because a short circuit prevents current.

Solution & Explanation:Using I = V/R gives 24 V / 0.12 ohm = 200 A. Such a large current can overheat conductors quickly, so fuses, breakers, and current-limited supplies are important.
