Series and Parallel Circuits

Two Important Terms Battery - Energy source (produces electricity) Switch - Device that controls whether or not electric current flows through a circuit

Different Types of Circuits Complete Circuit - Current flows in a complete circle. Flows from battery, to bulb, back to battery Incomplete Circuit - Path of electricity flow has been broken. - Electricity stops and bulb will not light

Continued Closed Circuit - Complete circuit, but a switch is used to close the circuit - Current goes from battery, through the switch, through the lights and back to the battery Open Circuit - Switch is open so circuit is incomplete = no light!

Draw a Circle On the circle, draw a battery On the opposite side, draw a bulb Which way is electricity flowing? - From negative to positive

Series and Parallel Circuits Series Circuit - Current travels along a single path to two or more electric devices (batteries, bulbs, switches) Parallel Circuit - Current travels along two or more paths to different electric devices.

Series Circuits “When one goes, they all go!” - ex: Flashlights, old Christmas lights All operate on the same current - More lights->Bulbs get “dimmer” - Series = All in one row ->Train

Parallel Circuits Current “splits” - Has more than one way to go around Commonly used in homes
