Types of Circuit & Brightness

Series Circuit

Components are connected in a single loop; one path for electron flow (It = I1 = I2)

Series Current

The current is the same everywhere in the circuit

Series Voltage

Voltage is divided amongst the components (Vt = V1 + V2 + V3)

Parallel Circuit

There are multiple branches/pathways; separate pathways for electrical current flow

Parallel Current

Total current is split up among parallel branches (It = I1 + I2)

Parallel Voltage

Voltage remains the same across branches; each component receives full voltage (Vt = V1 = V2)

Brightness: Series

As more bulbs are added, they get dimmer because voltage is shared; if one bulb goes out, the rest go out

Brightness: Parallel

Bulbs will remain the same brightness no matter the amount of bulbs; if one fails, others remain unaffected
