Thank you very much. I've been away from this stuff for so long that it makes me question my methods at times.

Hello everyone. I wanted to make sure I did this problem correctly. The problem is this: A light with an intensity of 75 W/m^2 is shone through three polarized lenses. The first lens is tilted at a 37 degree angle, the second is at a 10 degree angle and the final lens is titled by 82 degrees...

Ah, I see. Thank you all very much. That was very helpful.

Yeah. Shoulda included that earlier. I was hoping it was more of a conceptual question. We have a 1.5 V battery powering a circuit on a breadboard that's got a 47 kiloohm resistor and a 33 microfarad capacitor in it. The resistor and capacitor are in series and the test leads of the oscilloscope...

I've thought and thought and thought about this, but I can't figure it out. How might I be able to estimate the apparent resistance of an oscilloscope? We're dealing with an oscilloscope connected to a circuit which uses a resistor and a capacitor. I think this question might have something to...

Thank you very much, especially for pointing out the error in my math. That's a big help.

Hello, I've done all of the calculations on my homework assignment and have gotten what seem to be the mathematically correct answers, but I'm not sure that they logically make sense. This is the diagram and the problem: You are standing on train tracks in such a way that a circuit is...

Thank you! It's great to be able to verify that I got the right answers.

Ah, I see. Thank you so much for your help.

Another question came up in the same problem. I guess I don't understand exactly how to calculate the current through the 10 ohm resistor. I get 12 amps doing it the way I thought would be right, but that's a whole lot larger than the total current (4.61). Are the current values not additive...

Thank you. I thought that might be the case in the beginning, but I wasn't entirely sure. Thank you again.

Thank you. That's what I needed to know. So can I treat the 4 and 17 ohm resistors as one resistor if I use the combined current value? Not sure if I worded that correctly, hopefully I did.

Right, but the cables from the 4 and 17 ohm resistors meet again before heading on to the 21 ohm resistor. So I'll need the current at the joint (at least for the voltage drop at the 21 ohm resistor), right?

But the resistors that are a problem (4 and 17 ohms) aren't in series, so how can I add them?

Problem with current and parallel resistors. Please help! Ok, I've got this homework problem that I'm somewhat stuck with. The problem relates to the picture below: I've got to figure out the total resistivity (done that), total current (done that), the current through the 21 ohm resistor...
