Lesson: Electric Current 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 use the formula I = Q/t to calculate the current through a point in simple circuits given the charge moving past that point in a given time.

Lesson Plan

Students will be able to

recall that electric charge is measured in coulombs,
recall that electric current is measured in amperes (A),
understand that electric current is the flow of electric charge,
understand that in a typical electric circuit, current is the flow of negatively charged electrons along the wires,
understand that the negatively charged electrons do move, but the positively charged nuclei do not,
understand that conventional current is in the opposite direction to the movement of electrons and that this is because historically it was thought that the positive charges were moving, but this was later proven to be incorrect,
use in all permutations.
