A. Prices moment
3:10 sinusoidal wave image created in the form of pie charts and sinusoidal wave. The pie chart is divided into eight sections that each segment of magnitude 45 0
Price instantaneous sinusoidal wave to a rotation angle stated:
B. Price Average
The average price of alternating current or voltage is obtained by calculating the average price for a moment, by counting of half period only.
Table 3.2 price sinusoidal wave
Average price equation:
C. Price Effective
3:11 Effective price image of a voltage / alternating current (AC) is equal to the magnitude of the voltage / current (DC) on a prisoner, which both produce the same heat. PLN 220 V voltage is the voltage effective, not price nor instantaneous voltage and the maximum voltage value.
Figure 3.12: The peak value, the effective value of a sinusoidal wave.
To calculate the effective voltage and current at sinusoidal waveform image obtained 3:12.
