Question

according to Ohm's law which of the following statement is true a) resistance increases as current increases b) resistance decreases as current decrease c)resistance increases as voltage increases d l V graph is liner​

Answer 1

option (c)

as per formula,

V=ir

voltage and resistance are directly proportional.

Answer 2

Answer:

As Resistance = voltage/ current

Therefore if R is constant then graph between V and I is linear line inclined to current at 45°.

But as resistance is directly proportional to voltage

Therefore if voltage increases Resistance increase only if current decreases.
