    How Does Adding a Resistor Affect Power Dissipation in a Parallel Circuit?

    12W 6W 10W 5W No enough info I am starting to think that 12W is the correct answer since there is no internal resistance in the battery.

    How Does Adding a Resistor Affect Power Dissipation in a Parallel Circuit?

    The other options are just numbers like 10W, 5W, etc. and there is no option for "Power doesn't changed" so I think the only option I have is "Not enough info" because I can't justify choosing the options with numbers.

    How Does Adding a Resistor Affect Power Dissipation in a Parallel Circuit?

    So if it doesn't change, the question becomes: "You have a circuit with a single resistor of resistance R connected to a battery that has zero internal resistance and has a power output of 12W. How much power is now dissipated in the original resistor?" Is it possible to know the power...

    How Does Adding a Resistor Affect Power Dissipation in a Parallel Circuit?

    Homework Statement You have a circuit with a single resistor of resistance R connected to a battery that has zero internal resistance and has a power output of 12W. A resistor of resistance of 6R is now connected in parallel to the original resistor. How much power is now dissipated in the...

    How can I self study a subject effectively?

    That is how I usually feel to be honest, there are many topics that I am super interested in that are either not offered at my university or are offered in 3rd/4th year or master level. Could you please tell me how you self-learned complex analysis and graph theory? What resources did you use...

    How can I self study a subject effectively?

    Thank you for the reply Choppy. Although my university is supposed to be a top tier university, I find the online courses, especially those by MIT, to be far better than what my university offers in every way. If I wanted to take maths classes that serve as the equivalent of that MIT...

    How can I self study a subject effectively?

    There are some classes that are not offered at my university, which I want to self study. How can I self study them effectively to get the same benefit as doing the class at university? There is this class MIT 6.024j Mathematics for Computer Science which I very much want to take online...

    Partial Fraction Decomposition

    Yes, definitely, it can all be skipped but the question is specifically asking for why it works.

    Potential difference in uniformly charged cylinder

    Thank you for your help Simon. I managed to get the right answer.

    Partial Fraction Decomposition

    \frac{x+2}{(x+1)(x+3)^{2}}\equiv \frac{A}{(x+1)}+\frac{Bx+D}{(x+3)^{2}} \equiv \frac{A}{(x+1)}+\frac{B(x+3)-3B+D}{(x+3)^{2}} \equiv \frac{A}{(x+1)}+\frac{B}{(x+3)}+\frac{-3B+D}{(x+3)^{2}} \equiv \frac{A}{(x+1)}+\frac{B}{(x+3)}+\frac{C}{(x+3)^{2}}

    Programs Advice for Someone Considering Double Majoring

    If you are worried about the workload, which is a lot, why not just take the subjects you like from physics and not double major? When you major in physics, you will be forced to take classes that you may not be interested in like Labs, E&M, QM, statistical mechanics, etc. I am double majoring...

    Potential difference in uniformly charged cylinder

    Yes, I did that a few weeks ago. The electric field due to an infinite (very long) line of charge is: \frac{\rho }{2\pi R \epsilon_{0}} If I substitute this into the equation for potential difference, I get: \Delta V = -\frac{\rho }{2\pi \epsilon_{0}}ln(R) Is this correct?

    Is complex analysis necessary for electrical engineering?

    I think I will read that book too, I already have it. I was initially planning on double majoring in math and CS, then changed my mind to EE and CS with 7 maths electives and it looks like I am going to go down to 6 maths electives...
