8.6 Series Circuts And Parallel Circuits Flashcards
1
Q
Whats series circuit, parallel circuit
A
Two bulbs in single-path circuit
Two bulbs in circuit w branches, connected in parallel
2
Q
One bulb removed
Series vs parallel
A
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
3
Q
Why are parallel circuits useful
A
Device in each branch operates independently
4
Q
Current in series, parallel circuit
Voltage in series, parallel circuit
A
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)
