the voltage across a capacitor is given by find expressions for the current, power, and stored energy. sketch the waveforms to scale versus time.

Respuesta :

The loss of voltage brought on by the passage of current through a resistance is known as voltage drop.

What is Voltage Drop?

  • The cable's resistance and reactance grow proportionately with its length.
  • This means that VD is a problem that is especially prevalent where there are long cable runs, such as in large buildings or on expansive properties like farms.
  • In any single phase, line to line electrical circuit, this technique is frequently used to size conductors properly. Use a voltage drop calculator to determine this.
  • Current flowing through electrical cables is always impeded or met with resistance. VD is defined as the voltage loss (in volts) caused by cable "impedance" that occurs throughout all or a portion of a circuit.
  • Insufficient VD can result in lights that flicker or burn dimly, heaters that heat inefficiently, and motors that run hotter than necessary and eventually burn out. In this situation, less voltage is pushing the current, which makes the load work harder.
