Sneaky Design


I received the prize today (for electronic design) that I previously blogged about: a sophisticated device which measures inductance, capacitance, and resistance (an LCR meter). I thought I would throw the ultimate challenge at it -- a small halogen bulb (see photo). Such bulbs have both inductance AND resistance, and both are so low that either could represent an impossible challenge. My new meter thought for several seconds, then reported: “Low Resistance and Inductance: Resistance 0.4Ω, Inductance 0.2μH.” OBSERVATION: VERY clever! Well done to the designers, Peak Electronic Design Ltd.
