2.1.4 Resistors

How is the resistance of a component calculated from potential difference and current?

A

Its resistance changes, so current is not directly proportional to potential difference.

B

R=VIR = \dfrac{V}{I}R=IV​, where VVV is potential difference and III is current.

C

R=IVR = \dfrac{I}{V}R=VI​, where VVV is potential difference and III is current.

D

R=VIR = V IR=VI, where VVV is potential difference and III is current.
