Three inductors are connected in series. Inductor 1 has an inductance of 0.6 H, Inductor 2 has an inductance of 0.4 H, and Inductor 3 has an inductance of 0.5 H. What is the total inductance of the circuit?
\mathrm{L}_T=0.6 ~\mathrm{H}+0.4 ~\mathrm{H}+0.5 ~\mathrm{H}
\mathrm{L}_{\mathrm{T}}=1.5~ \mathrm{H}
