Modelling Resistance in Series Circuits (VCE SSCE Physics): Flashcards

Measure of how much a material impedes current flow

Ohm ($Omega$)

$V = IR$

Straight line through the origin

Curved (non-linear)

Same through all components

$R_{ ext{equivalent}} = R_1 + R_2 + R_3 + ...$

V_{ ext{out}} = rac{R_2}{R_1 + R_2} imes V_{ ext{in}}

Lowest possible (ideally zero)

Very high (ideally infinite)
