Graph of Current v Voltage

APPH12-YTG39B

A student connects a single resistor to a variable voltage source, then uses an ammeter to measure the current through the resistor at increasing voltages. The student’s data is shown in the graph above.

Use these data to calculate the value of resistance.

A

$0.045 \space \Omega $

B

$22 \space \Omega $

C

$7.0 \space \Omega $

D

$1.6 \space \Omega $
