What will be the resulting current when a voltage of 115 VDC is applied to a resistance of 12 ohms in figure "A" of the illustrated circuit with the switch closed? Illustration EL-0018

Correct Answer: Option C — 9.58 amps

Direct current circuit calculations using Ohm's law ($I = \frac{V}{R}$) require dividing 115 volts by 12 ohms, yielding 9.58 amperes. This standard mathematical relation complies with IEEE 45 and 46 CFR Subchapter J standards for analyzing basic shipboard DC electrical circuits and conductor sizing.
