MHT CET 2025 Physics question
When a current in the conducting coil is changed from 5 A in one direction to 5 A in opposite direction in 0.5 second, an average induced e.m.f in the coil is 2 V. The self-inductance of the coil is
Answer: (D)
Solution
The current changes from A to A, so the total change is A in s. The average induced emf is , so \dfrac{e Δ t}{Δ I}\dfrac${2×
