(A) The formula for the average induced $e.m.f.$ in a coil due to self-inductance is given by $|e| = L \left| \frac{di}{dt} ight|$.Here,the change in current $di = 10\,A - (-10\,A) = 20\,A$.The time interval $dt = 0.5\,s$.The induced $e.m.f.$ $e = 1\,V$.Substituting these values into the formula:$1 = L 	imes \frac{20}{0.5}$$1 = L 	imes 40$$L = \frac{1}{40}\,H = 0.025\,H$.Converting to millihenry $(mH)$:$L = 0.025 	imes 1000\,mH = 25\,mH$.

An average induced $e.m.f.$ of $1\,V$ appears in a coil when the current in it is changed from $10\,A$ in one direction to $10\,A$ in the opposite direction in $0.5\,s$. The self-inductance of the coil is.....$mH$.
