Batteries can be connected together in various combinations to increase their total voltage and/or total current. Connecting batteries in **series** combines their voltage while keeping their current the same, connecting batteries in **parallel** combines their current while keeping their voltage the same, and using a **series-parallel** configuration, half the batteries can be connected in series and half in parallel to combine both voltage and current.

Ohm's law specifies the relationship between voltage (V), current (I), and resistance (R) in an electrical circuit: **V = IR**.
