Answer :
A series connection is made between four inductors, each of which has an inductance of 0.6 h. so the circuit's overall inductance is 2.4h.
Since the current change through each coil is the same, the inductance of inductors that are connected in series is computed as the sum of the individual inductances of each coil. L di/dt = V. Accordingly, the individual inductances of each inductor are added to determine the overall inductance of the series connection.
Let the four inductors be L1 = L2= L3= L4 = 0.6h
Given that inductance of each inductor = 0.6h
We are aware that LTotal = L1 + L2 + L3 +... + Ln is the formula for the total inductance of a series.
LTotal = L1+L2+L3+L4 = 0.6+0.6+0.6+0.6 = 2.4h is the total inductance.
