At what rate a single conductor should cut the magnetic flux so that current of 1.5 ~mA flows through it when a resistance of 5 is connected across its ends?
Options
- A6 10⁻³ wb s
- B8 10⁻³ wb s
- C4 10⁻⁴ wb s
- D7.5 10⁻³ wb s
Correct answer
D. 7.5 10⁻³ wb s
Step-by-step solution
aligned & I = e R or e = IR & e = d dt d dt = IR =1.5 10⁻³ 5 & =7.5 10⁻³ ~Wb / s aligned
