Diagram bellow shows the graph of potential different, V against current, I, for three
different conductors, P, Q and S.
Rajah di bawah menunjukkan graf beza keupayaan V melawan arus I bagi tiga konduktor P,
Q dan S.
Which statement about the conductors is true ?
Pernyataan manakah betul mengenai konduktor-konduktor tersebut?
A P has a lower resistance than S.
P mempunyai rintangan lebih rendah daripada S.
B Only conductor Q obeys Ohm’s law.
Hanya konduktor Q mematuhi hukum Ohm.
C The resistance of Q increases with current.
Rintangan Q bertambah dengan arus
D The resistance of P increases with current.
Rintangan P bertambah dengan arus.
