Re: Circuit Lab B/C

Does anybody a good circuit analysis textbook that contains no calc or trig (trying to get one suitable for Div B 6th graders). Thank you so much in advance! Physics by Giancoli does not use any calculus or trig in their DC Circuits chapter. That being said, it could more advanced than you might li...

Re: Circuit Lab B/C

Uh what happens if you place the black lead closer to the voltage source and the red lead on the other side of the resistor (when measuring voltage across a resistor)? This should just give the negative value for voltage, but the magnitude should be the same right? Yes. Assuming your black lead is ...

Preparing for the Lab Portion

It looks like this question has been asked several times by several different people. Most of our answers have been fairly vague and general (e.g. "look at released exams" and "do more practice"), so I thought I would write up a more thorough answer based on what I've seen so far during the season. ...

Re: Write It Do It B/C

How do you get good at writing quickly? From my experience, the key to doing well is not to get good at writing more or writing faster but rather to increase the information density of your writing. The rules allow for abbreviations which should dramatically speed up the writing process. My partner...

Re: Circuit Lab B/C

Quick question, are event supervisors allowed to restrict the multimeter you use in labs or prevent you from using your multimeter altogether? I was thinking about practicing with worse multimeters in case I had to use one in competition. Rule 2d addresses this issue. It appears that it's up to the...

Re: Circuit Lab B/C

Does anyone know what a placing score would be at MIT? Hello! I'm not the actual day-of ES for Circuit Lab at MIT, but I wrote a few of the exam questions and the lab portion for the MIT Invite. We won't be giving many details about raw scores at the moment, but I can give you some general benchmar...

Re: Circuit Lab B/C

As drawn, the 12 and 6 ohm resistors are in parallel, so can be replaced by a single 4 ohm resistor. The right hand loop on the picture is irrelevant, as the diode is reverse biased and does not conduct (proof left as an exercise for the reader). So you have a simple loop circuit with a diode and 7...

Re: Circuit Lab B/C

Question|What cases do kirchoff's law not apply? They always apply? No, there are some cases where they don't apply. With KVL, it doesn't apply with a varying magnetic field, and with KCL, it doesn't apply when the voltage source has a very high frequency. Anyways, your turn! So this isn't relevant...
