Three inductors are connected in parallel. Inductor 1 has an inductance of 2.5 H, Inductor 2 has an inductance of 1.8 H, and Inductor 3 has an inductance of 1.2 H. What is the total inductance of this circuit?
\mathsf{L_{T}} = {\frac{1}{{\frac{1}{2.5\ \mathsf{H}}}+\ {\frac{1}{1.8\ \mathsf{H}}}+{\frac{1}{1.2\ \mathsf{H}}}}}
\mathsf{L_{T}} = {\frac{1}{(1.788)}}
\mathsf{L_{T}} = 0.559 H
