2.1.4 Resistors

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.
