Current

This is lab 5 of 17 in the course

by Enable Education

In this lab, students will learn about the concept and properties of current. Students will simulate circuits with ideal voltage and current sources and experiment using Ohm’s law to understand how current is derived from known voltages and resistances. Finally, students investigate Kirchoff’s Current law and the result of having multiple current pathways.
