<previous   BASIC AC THEORY 6   next> RESONANCE In the chapters on inductance and capacitance we have learned that both conditions are reactive and can provide opposition to current flow, but for opposite reasons. Therefore, it is important to find the point where inductance and capacitance cancel one another to achieve efficient operation of […]

<previous   BASIC AC THEORY 5   next> IMPEDANCE Whenever inductive and capacitive components are used in an AC circuit, the calculation of their effects on the flow of current is important.                       <previous   BASIC AC THEORY 5   next>

<previous   BASIC AC THEORY 4   next> CAPACITANCE There are many natural causes of capacitance in AC power circuits, such as transmission lines, fluorescent lighting, and computer monitors. Normally, these are counteracted by the inductors previously discussed. However, where capacitors greatly outnumber inductive devices, we must calculate the amount of capacitance to add or […]
