Circuits and Circuit Diagrams (HSC SSCE Physics): Flashcards

Connections between components using standard symbols

$\sum V = 0$ around any closed loop

$\sum I_{in} = \sum I_{out}$ at junctions

Energy

Charge

$R_{total} = R_1 + R_2 + R_3 + ...$

$\frac{1}{R_{total}} = \frac{1}{R_1} + \frac{1}{R_2} + ...$

Constant throughout (same through all components)

Same across all parallel components

Decrease (always less than smallest resistor)
