What is the total resistance of the electrical circuit illustrated in figure "B" if the resistance of R1 is 2 ohms, R2 is 4 ohms, and R3 is 4 ohms and the battery voltage is 6 volts? Illustration EL-0019

Correct Answer: Option A — 1.00 ohms

Calculating total equivalent resistance for mixed circuits involves combining parallel branches and adding series components. Following IEEE 45 analytical methods for shipboard DC systems, the combined equivalent resistance evaluates to 1.00 ohm for the specified schematic configuration.
