THE CHALLENGE

For a circuit with many meshes, how do you find the current for each mesh?

GENERATE IDEAS

Provide the challenge and ask for opinions from the students

MULTIPLE PERSPECTIVES

The students work for 10 minutes and come up with ideas

RESEARCH & REVISE

The teacher introduces the definition of a Laplace transform and explains some key points in the definition. Then, the teacher give several examples on how to find Laplace transforms for several typical functions in the time domain.

TEST YOUR METTLE
