14 cards from this deck
Current
Potential difference
Resistance
R=VIR = \frac{V}{I}R=IV
Ohms (Ω)
Volts (V)
Amps (A)
Current and potential difference are directly proportional
Straight line through the origin
Wire heats up, metal atoms vibrate, increasing resistance
One direction only
Threshold voltage
Very high for all potential differences
Resistance drops rapidly, current increases rapidly
