Lesson: Alternating Current Circuits Physics • Third Year of Secondary School

Join Nagwa Classes

Attend live Physics sessions on Nagwa Classes to learn more about this topic from an expert teacher!

In this lesson, we will learn how to determine the values of electrical quantities in circuits powered by alternating voltages.

Students will be able to

use the formula to calculate the induced emf due to the rotation of a conducting coil in a uniform magnetic field,
calculate root-mean-square values of alternating voltage, current, and power,
identify the phase relationship between voltage and current in alternating current circuits that are either resistive, capacitive, or inductive.
