What will you get when connecting four 6V, 200 amp DC batteries in parallel?

12V DC, 400 amps
6V DC, 800 amps
12V DC, 800 amps
6V DC, 200 amps

The correct answer is: 6V DC, 800 amps

When connecting batteries in parallel, the voltage remains the same as that of a single battery, while the capacity (measured in amp-hours or amps for the application) adds up. In this case, since you are connecting four 6V batteries in parallel, the overall voltage of the system is still 6V. The capacity increases with each additional battery connected in parallel. Each battery has a capacity of 200 amps, so when you connect four of them, the total capacity becomes 200 amps multiplied by 4, resulting in 800 amps. Therefore, the system will yield 6V DC with a total capacity of 800 amps. This understanding is critical when designing or troubleshooting electrical systems, as knowing how voltage and current interact in these configurations ensures that the system operates safely and efficiently.
