A 6-V battery powers a circuit with parallel branches on a board. Several wires and light bulbs plug into the board to make various series and parallel circuits. The brightness of the bulbs changes ...

In series circuits, the current is the same through each component. The potential difference of the power supply is shared between the components. A parallel circuit showing two bulbs, a switch ...

Two lamps connected in series with ... same throughout a circuit and voltages add up to the supply voltage. Components that are connected on separate loops are connected in parallel.
