### What are the functions of these capacitors connected to the output of a efuse?

C5-C6 as well. Or, you could equally well ask: why are C3 and C4 equal here? The topic is PDN (power distribution network) analysis, and I won't go into detail here (as hard as that may be to believe,...

### Inductor and capacitor in parallel should not yield resultant current in phase w/ voltage

"Inductive load" here means a load with an overall inductive component to its current in addition to any in-phase current, not a purely inductive load. I.e. a phase angle between 0 and +90. ...

### Why does the reciprocal of sum of reciprocals relationship appear commonly?

It simply means that the unit you're using for this measurement is the reciprocal of the quantity that you're actually adding. When you put two resistors in series, you're literally adding more ...

### Why does the reciprocal of sum of reciprocals relationship appear commonly?

It appears in many contexts, as it's the sum of the harmonic mean of the elements, one of the ways of finding the "most normal value" of a set of values. Typically it's used for rates, such ...

### How is the reactance of a capacitor formulated?

In an ideal capacitor, there are no parasitic resistances so the real component to the impedance is just zero and the phase angle is -90 degrees or -j. It can also be written as Z = 0 - jωC. In real ...

### What are the functions of these capacitors connected to the output of a efuse?

The boost converter TPS61085 has Cout recommendations. 2x10uF is recommended as usually working well. The loop response is dependent on Cout as well as feedback components, but those relationships ...
