TRANSFORMATOR dan TEGANGAN AC
The document contains calculations related to voltage in alternating current (AC) systems, specifically rms (root mean square), peak voltage (vmax), and frequency. It explains how to derive various parameters from given values, such as converting rms voltage to peak voltage and calculating frequency from period. The calculations involve basic formulas in electrical engineering for AC voltage and wave characteristics.
