This is similar to problem 2.36 in "Circuit Analysis and Design" by Ulaby, Maharbiz, and Furse. This is a free/open educational textbook on basic circuit design found here: https://cad.eecs.umich.edu/
We will use our knowledge of series and parallel resistors to simplify the circuit. Finally we will also use a source transformation to further simplify the problem. This procedure is known as making an equivalent circuit. This is a common type of introductory engineering electric circuits problem.
On this page of the site you can watch the video online Equivalent Circuits & Source Transformation Example Problem with a duration of hours minute second in good quality, which was uploaded by the user Dr. Chrysler's Engineering Education Channel 19 January 2023, share the link with friends and acquaintances, this video has already been watched 331 times on youtube and it was liked by 1 viewers.
