8.6 Series Circuts And Parallel Circuits Flashcards
Whats series circuit, parallel circuit
Two bulbs in single-path circuit
Two bulbs in circuit w branches, connected in parallel
One bulb removed
Series vs parallel
Other goes out; 1 path for current to flow, opened circuit, no current flow, bulb doesnt light up
Other still lights; current still flow through other branch
Why are parallel circuits useful
Device in each branch operates independently
Current in series, parallel circuit
Voltage in series, parallel circuit
Same at diff points; 1 path, same current flows through all points
Main loop current = branch 1 + branch 2 (lm=l1+l2)
Voltage across diff circuit components are diff (bulb ≠ cell)
Same across every branch (each branch=cells v) (v1=v2=vm)
