III. Electrical Circuits Ch. 21 - Electricity III. Electrical Circuits (p.608-613) Circuit components Series circuits Parallel circuits Household circuits

A. Circuit Components A - battery C - light bulb B - switch D - resistor

B. Series Circuits Series Circuit current travels in a single path one break stops the flow of current current is the same throughout circuit lights are equal brightness each device receives a fraction of the total voltage get dimmer as lights are added

C. Parallel Circuits Parallel Circuits current travels in multiple paths one break doesn’t stop flow current varies in different branches takes path of least resistance “bigger” light would be dimmer each device receives the total voltage no change when lights are added

D. Household Circuits Combination of parallel circuits too many devices can cause wires to overheat Safety Features: fuse - metal melts, breaking circuit circuit breaker - bimetallic strip bends when hot, breaking circuit
