GROUP 1 Q1 Battery Group . 2 questions This assignment is very important to prepare you for the assessment at the end of the week. You will want to work on these problems as you go over the material for the week. It is not something you can complete correctly in a couple hours without a strong physics background. 1. Start by attempting to solve each of the questions, and keep your work! Submit the assignment. 2. After submitting, the correct answers and hints will be immediately visible to you. Go back and rework all of the questions you got wrong using the hints and correct answers to help. 3. If you are completely stuck you can look up the full solution in the provided solutions document but only do this as a last resort. 4. Submit pictures/scans/PDFs of each of the problems you missed, correctly worked out, in that week's test to earn back the points for that question and raise your practice problem assignment grade!

Mini lecture with captions For the circuit below, each individual resistor has 2 Ohms of resistance. E G J Text description of the circuit above. Starting at the battery, the wire goes through one resistor to point K. After point K the wire splits into a top, middle and bottom main branches. The top main branch starts at point Can then splits into a top and bottom small branch. The top small branch has one resistor. The bottom small branch starts with point A, has 2 resistors in a row, and then point B. The 2 small branches reconnect at point D, goes though a resistor and the top main branch ends at point E.The middle main branch starts at point F, has 3 resistors in a row and ends at point G. The bottom main branch starts at point H, splits into 2 small branches that have one resistor each before recombine at point I. It then goes though 2 more resistors to pointJ. All three main branches then come back together at point L and then the wire returns to the battery. QUESTION 4.1 Find the total resistance (equivalent resistance) between A and B (two resistors).
