Series and parallel circuits Quiz Practice Quiz…

The current is the same through all components. — Current is constant in a series circuit because there's only one path for it to flow.

The voltage is the same across all branches. — Voltage is constant across parallel branches because they share the same two connection points.

The total resistance increases. — Adding resistors in series increases the total resistance; they add linearly.

3.33 ohms — Parallel resistors' total resistance is less than the smallest individual resistance: 1/Rt = 1/R1 + 1/R2 + 1/R3

Parallel circuit — Parallel circuits have multiple pathways for current to flow, unlike series circuits.
