Combing hair with a wood comb typically results in the hair becoming positively charged while the comb acquires a weak negative charge due to the transfer of electrons. The triboelectric series supports this phenomenon, indicating how different materials interact electrically. A user conducted a voltmeter test, measuring positive voltage when touching hair and negative voltage when touching the wood comb, leading to confusion about the interpretation of the results. The discussion seeks clarification on whether the measurements align with the expected electrical behavior after combing. Understanding the triboelectric effect is crucial for interpreting these observations accurately.
