Learning Outcomes for Electric Circuits

 

Lesson Plans || Learning Outcomes and Activities || Teacher Notes || Labs

The list below displays sample learning objectives for the unit on Electric Circuits. The various activities from the Lesson Plans have been organized by objective. This format of organizing The Physics Classroom's activities may be more useful to some teachers than the Lesson Plan format. It is worth noting that the activities identified below only include those activities included on the Lesson Plans and in the Pre-Built Task Tracker courses. Additional activities are referenced on the Teacher Notes page.


 

1. Electric Potential and Electric Potential Difference

Relate electric potential to the energy per charge and the electric potential difference between two locations to the change in energy per charge moved between the two locations; identify the units of electric potential and distinguish between high and low potential locations.

2. A Model of Charge Flow in a Circuit

Identify the two requirements of an electric circuit; describe charge as marching together through the circuit loop at the same rate at every location, never accumulating nor being used up; describe the conducting components (wires, bulbs, batteries, etc.) of the circuit as being the source of charge and describe the battery as being the energy source that is used to pump the charge uphill from low energy to high energy to establish an electric potential difference across the two ends of the external circuit..

3. Current

Define current and identify its unit; mathematically relate current to the quantity of charge and the time; identify the direction of conventional current and compare the current near the + terminal of the battery to the current at all other locations within the circuit.

7. Series Circuits - Concepts and Mathematics

Discuss the meaning of equivalent resistance (R_eq) and calculate the R_eq value for a series circuit. compare the current and the electric potential at the various locations and relate the battery voltage to the individual voltage drops of each resistor; use ∆V=I•R to conduct a complete analysis of a series circuit.
