NUST NET Physics — Current Electricity
Current Electricity is part of the FSc Physics course that NUST NET-Engineering draws on (Physics is 60 of the 200 MCQs). It breaks into 4 subtopics, and we hold 87 NET-pattern practice MCQs on it, each with a written explanation. Tap a subtopic below to practise just that.

Current Electricity MCQs from the NET-pattern papers
Try each one before opening the answer. Each comes with a short explanation.
- Q1 · NUST NET Past Paper 07 · Current Electricity
The resistivity of a metal wire depends on:
- A.its length
- B.its material and temperature
- C.its cross-sectional area
- D.the current through it
Show answer
Answer: B. its material and temperature — Resistivity is a property of the material (and its temperature), not of the wire's size.
- Q2 · NUST NET Past Paper 08 · Current Electricity
The resistivity of a material depends on:
- A.the length of the sample
- B.the nature of the material and its temperature
- C.the cross-sectional area of the sample
- D.the current through it
Show answer
Answer: B. the nature of the material and its temperature — Resistivity is a property of the material (and its temperature), not of the sample's shape.
- Q3 · NUST NET Past Paper 05 · Current Electricity
For a uniform wire, the resistance is:
- A.directly proportional to its cross-sectional area
- B.independent of its length
- C.directly proportional to its length
- D.inversely proportional to its length
Show answer
Answer: C. directly proportional to its length — R = ρL/A, so R ∝ L.
