Question

Current in a circuit falls from 5 A to 0 A in 0.1 s. If an average emf of 200 V is induced, give an estimate of the self-inductance of the circuit (A) 2 H (B) 4 H (C) 6 H (D) 8 H

:|ε|=L ⋅ (Δ I/Δ t) 200=(L)((5/0.1)) ; L=((20/5))=4 H

Q. Current in a circuit falls from $5 A$ to $0 A$ in $0.1 s$ . If an average $e m f$ of $200 V$ is induced, give an estimate of the self-inductance of the circuit

$2 H$

$4 H$

$6 H$

$8 H$

$: ∣ ε ∣ = L \cdot \frac{Δ I}{Δ t}$
$200 = (L) (\frac{5}{0.1})$ ;
$L = (\frac{20}{5}) = 4 H$
