Card 1 of 23
How is the resistance of a component calculated from potential difference and current?
A
R=VIR = \dfrac{V}{I}R=IV, measured in ohms (Ω\OmegaΩ).
B
A resistor at constant temperature produces an I-V graph that is a straight line through the origin.
C
The component has constant resistance and is an ohmic conductor at constant temperature.
D
Its resistance decreases.
