Ohm’s Law (Grade 11 NSC Matric Physical Sciences): Flashcards

Current ∝ voltage at constant temp for metal conductor

$I = \frac{V}{R}$

$V = IR$

Rate at which electric charge flows, measured in amperes (A)

Energy per unit charge to move it, measured in volts (V)

Difficulty pushing current through, measured in ohms (Ω)

Straight line through origin

$\frac{1}{R}$ or $\frac{\Delta I}{\Delta V}$

In series

In parallel
