Research intent

A study records why the work exists before the measurements appear. Every run links that intent to instruments, conditions, raw files, and derived analysis.

STUDY

Buck-converter load sweep

Measure conversion efficiency and locate its observed peak across resistive loads.

efficiencyload-sweeppower-electronics
STUDY

First-order RC low-pass characterization

Estimate the -3 dB cutoff and quantify the effect of a resistor substitution.
