BPSC – Combined Competitive Examination · प्रश्न 104
Which of the following gives the resistance of a wire?
उत्तर दाखवा आणि स्पष्टीकरण
उत्तर: (C) R = V/I
स्पष्टीकरण
By Ohm's law V = IR, so R = V/I.
- (A) चूक
Wrong: IV is power, not resistance.
- (B) चूक
Wrong: not a valid relation.
- (C) बरोबर
Correct: Ohm's law: R = V/I.
- (D) चूक
Wrong: I/V is conductance.
