Capacitor Diagram Transormations

Click For Summary
SUMMARY

The discussion focuses on the transformation of a capacitor schematic involving a Y network and its equivalent Δ configuration. Each capacitor in the example is specified as 7pF, leading to a calculated equivalent capacitance (C(eq)) of 4.308pF. The conversation emphasizes the need for understanding impedance transformations and references specific figures to illustrate the process. An exercise is provided to reinforce the concepts discussed.

PREREQUISITES
  • Understanding of capacitor values and configurations

I am having a difficult time understanding how they're transforming this capacitor schematic...what exactly is going on here? The example states that each cap is 7pF and the final answer C(eq) = 4.308pF...but why?

There should be 3 figures to illustrate what the dialogue is describing, The first figure would be identical to that in your image #2. Then the Y network at its centre is transformed to Δ, producing the figure you have as image #1.

Finally, to consolidate the topic, they set you an exercise to apply what you have learnt, and this exercise is centred around your image #2.

You'll need the formulae for these impedance transformations, presumably your lectures have covered the topic? http://www.allaboutcircuits.com/vol_1/chpt_10/13.html
