Battery A has a voltage of 6 volts and a current of 2 amps, while Battery B also has a voltage of 6 volts and a current of 2 amps. When connected in series, the total voltage would be 12 volts, and the total current would remain at 2 amps.
A volt is a potential difference across a conductor when a current of one ampere (Amp) dissipates one watt of power.
