Whenever analysing a simple linear circuit, see what it does to a resistor. Here, think of connecting a resistor across 2 black boxes, one of them has a charged capacitor, and the other one has a capacitor in series with a voltage source. Now you connect the switch on them both at the same time...

Given a flexible wire loop of a certain perimeter and planar shape, what are some good ideas to minimise the loop's inductance? For example, would it work if i surrounded the wire loop with a superconducting loop in the same plane?

What is being done here, is that the load is being referred to the gear's output side. Let's say you had an object of moment of inertia L (load) being rotated through a lossless gear system of ratio N2/N1. If you apply Torque T as input, output torque is scaled by the gear ratio. Now if I ask...

What you are trying to do comes under the general idea of regenerative braking. A lot of semiconductor manufacturers have solutions for this. http://www.ti.com/tool/DRV8312-69M-KIT You basically need to load the alternator in a controlled manner to ensure you don't spend too much effort on...

Let's assume that your signal generator can generate both sine waves and square waves and supports a low impedance output. You already have the resistor value. Now connect only the LC part of the circuit across the signal generator outputs, and give a very low frequency square wave as an output...

For electronic components, try using www.digikey.com for a big part reference. It has a very comprehensive inventory and you should find the part you want there.

mdmartin: I am trying to make your question clear. Do you want to understand what happens to the field outside of the metal sphere when the sphere is introduced?

Choose a differential ring which is at a slant distance 'l' from the vertex and of thickness 'dl'. Now try and find out the force exerted by the point charge on the ring, not the other way round (this is simpler to calculate). Proceed along these lines and integrate over the cone. The final...
