Every E&M student needs to solve this problem.
If you're taking Electricity and Magnetism, it's almost guaranteed that you will need to solve a problem like this on at least one test or exam!
This video shows you step by step how to apply Kirchoff's Current Law and Kirchoff's Voltage Law to write the equations to solve for unknown currents in the circuit, and then (very quickly) shows you how to solve those equations.
