lesson 6: understanding the basic characteristics of ac circuits

However, we can still assume that power is equal to the amperes (i) times the voltage (v). As the load is increased on a shunt type generator, the output voltage will To control the output voltage of a shunt generator, an electronic voltage regulator is installed to sense changes in the output voltage and makes adjustments to the shunt field current. Direct current, also known as DC, is a type . An alternative to across-the-line motor starting is reduced voltage starting. The circuit shown here is a four-bit analog-to-digital converter (ADC). The voltage and the current we use in AC can be presented as the following equations: f = the ordinary or cyclic frequency = the number of complete oscillations per second.
