The rate of change of current which produces an induced emf of 100 V in an inductor of inductance 10 H is |
8 A/s 10 A/s 12.5 A/s 14 A/s |
10 A/s |
The correct answer is Option (2) → 10 A/s Given: Induced emf, $E = 100\ \text{V}$ Inductance, $L = 10\ \text{H}$ For an inductor, induced emf is given by: $E = L \frac{dI}{dt}$ Rearranging: $\frac{dI}{dt} = \frac{E}{L} = \frac{100}{10} = 10\ \text{A/s}$ ∴ Rate of change of current = 10 A/s |
