5 Questions
Explain the difference between DC and AC.
DC is the current which flows in one direction only and generally has constant magnitude, while AC is the current which periodically passes through a definite cycle of changes in respect of magnitude as well as direction.
Describe the advantages of AC.
AC can generate high voltage with less construction and operating per kW cost. It can also raise or lower voltage using a static device known as a transformer.
What are the learning outcomes of the session on AC fundamentals?
The learners will be able to differentiate between DC and AC quantities, describe the generation of alternating emf and current, and write equations for alternating emf and current.
Who is the author of the text on AC fundamentals?
Ganesh N. Jadhav
What is the equation for an alternating quantity?
$v(t) = V_m \sin(\omega t + \phi)$ where $V_m$ is the maximum value, $t$ is time, $\omega$ is the angular frequency, and $\phi$ is the phase angle.
