Unformatted text preview: UC Berkeley, EECS Department B. E. Boser EECS 40 Lab LAB1: Solar Power Supply UID: Enter the names and SIDs for you and your lab partner into the boxes below. Name 1 SID 1 Name 2 SID 2 Laboratory Organization The document you are looking at are the instructions for the first laboratory in EE 40. You will use similar instruc- tions for all labs. These instructions serve dual purpose as pre-lab instructions and lab guide. Here is what you have to do (take note of the different deadlines!): a) Preparation (“pre-lab”): Download the instructions and read them to be ready for the laboratory. For many labs you will be asked to analyze and design the circuits you will be building. Complete all these assignments before the lab and make sure to enter all your results into a printed copy of the lab instructions or on separate sheets appended to the instructions. Please get help in office hours before the lab if you have questions. You will not be permitted to start the lab if you do not come fully prepared. b) Online submission: Answers to numerical and textual pre-lab questions boxes are submitted online. Submit them by the due date listed by the grading machine . Usually this will be well before your lab. If you do not submit on time you will not receive credit. c) Laboratory: Follow the instructions and perform all required measurements. Ask the lab GSI for help if you have problems with equipment, parts, or your circuits. The GSI will not answer pre-lab questions during the lab. Please use office hours before the lab for this purpose. The instructions also ask for the GSI to verify certain measurements. Demonstrate your working circuit and ask the GSI to acknowledge its correct operation in the box provided. Feel free to try out your own experiments, time permitting. d) Report: Collect your measurement results, interpretations, etc. on the printed lab instructions and add addi- tional sheets as needed. Turn in the completed instructions with all questions answered to the lab GSI. You can do this at the end of the laboratory, or up to one week after the lab. Warning The laboratories in this course are designed to operate with voltages less than 25 V. Such low voltages when touched do not usually deliver sufficient energy to the human body to cause harm. However, the equipment we are using is capable of generating higher voltages and is plugged in to the high voltage household current grid (110 V-240 V) that is harmful when touched. Circuit components can also get hot; be careful to not get burned! Because of this, follow these precautions when working in the lab: a) Turn off the power when modifying a laboratory setup or performing manipulations that could expose you to high voltage....
