a. Why does external voltage increased with decreasing current with seperate excitation?
b. Why does external voltage decrease more with shunt than with seperate excitation?

i just reading an analogy for Ohm's Law about current and voltage, but i still didn't understand clearly "With resistance steady, current follows voltage (an increase in voltage means an increase in current, and vice versa)". it is say that when voltage increase so the current increase too with resistance steady.
I have a straing gauge circuit containing an INA126 amplifier. The design is to use 5V however, I only have a 12V power supply available (from the wall), and was going to use an LDO to control the voltage to 5V.
A group of students along with myself are working on a DC-DC Converter with an MPPT as our Senior Design Project. After a few weeks of thinking through differing designs we decided to go with one which implements the MPPT first and then sends the output voltage and current to a DC-DC converter to adjust the voltage for a battery to be charged at a constant voltage.
My professor asked me to also find the voltage drop V2(t) across the middle section using voltage divider (it's a section consists 30ohm in parallel to the 5mF capacitor).
I found V(t) across current source, but I don't get the point of using voltage divider to get V2(t). Can't I just use the current going through the middle section and use ohm's law to find V2(t)?
Is there a program that displays UnCore Voltage inside Windows?
I'm thinking about overclocking my 4670K and although i can monitor Core Voltage with CPU-Z i would like to know where UnCore goes under load (Prime95).
Or Uncore Voltage follows Core Voltage (give or take a few mV, at least at Auto Voltage) and i shouldn't bother?
Monitoring L3 Cache Frequency would be nice too...
