The initial rate of rise of current through a coil of inductance 10 H when suddenly connected to a D.C. supply of 200 V is__________Vs
Correct answer: B. 20
- A. 50
- B. 20
- C. 0.05
- D. 500
Explanation
For an inductor, the initial current slope is given by di/dt = V/L = 200/10 = 20 A/s. The printed unit “Vs” is likely a typographical error for A/s.
