Find the power delivered by the 2 A current source in this circuit. Normally, I would suggest using the mesh current method (mesh analysis) to solve this problem, but here I present the source transformation method. The reason I opted for this technique is that it sheds light on a very important point in circuit analysis: whenever you simplify or transform a circuit, it helps a great deal to make sure that any labelled quantities would still be intact — that is, you would still explicitly see th

Precision current measurement is essential for optimizing performance...
