If you connect two 12 volt batteries in parallel, what will be the result in terms of voltage output?

Connecting two 12-volt batteries in parallel maintains the same voltage as a single battery while effectively doubling the available current (amp hours) from the batteries. When batteries are wired in parallel, the positive terminals are connected together, and the negative terminals are connected together, resulting in a combined system that offers increased capacity without altering the voltage. Therefore, the output remains at 12 volts DC (VDC), which is the same as each individual battery.

The other voltage-related options suggest an output of 24 volts, either in direct current (DC) or alternating current (AC), which would only occur if the batteries were connected in series, not parallel. In this case, the output is correctly identified as 12 VDC, as it reflects the design of parallel configurations.
