15 cards from this deck
How current changes when potential difference is altered
Vertical y-axis
Horizontal x-axis
Constant (doesn't change)
Straight line through the origin
Linear relationship
Filament gets hotter and vibrates more, resistance increases
Curved line that gets less steep (non-linear)
One direction only (forward direction)
Around 0.7V
Flat then straight line
To change the potential difference
Lower resistance
R=VIR = \frac{V}{I}R=IV
