When combining batteries, connecting them in series adds their voltages, but keeps the amp-hour (Ah) capacity the same. In parallel, the voltage remains constant, while the Ah doubles. Be careful; mixing different voltage batteries in parallel can harm them, as current flows from higher to lower voltage batteries. In contrast, connecting batteries in parallel keeps … Read more

Voltage is the electric potential difference that measures energy per unit charge. The electric field is the force experienced by a charge in that field. In a battery, voltage creates an electric field by separating positive and negative charges. Higher voltage leads to a stronger electric field, driving the current through the circuit. The electric … Read more
