v=IR

The Attempt at a Solution


I have tried finding the total resistance of the circuit and then applying ohms law. My answer is 0.65 Amps but that's incorrect.

Any help is much appreciated!

Hi qwerty2x! :wink:

Show us your full calculations, and then we can see what went wrong, and we'll know how to help! :smile:
 
Use the equivalent resistance formulas and then Ohm's Law

For two resistors in series R_{eq} = R_{1} + R_{2}
For two resistors in parallel \frac{1}{R_{eq}} = \frac{1}{R_{1}} + \frac{1}{R_{2}}

or two resistors in parallel simplified R_{eq} = \frac{R_{1}R_{2}}{R_{1}+R_{2}}}

Hope this helps!
 
Thread 'Need help understanding this figure on energy levels'
This figure is from "Introduction to Quantum Mechanics" by Griffiths (3rd edition). It is available to download. It is from page 142. I am hoping the usual people on this site will give me a hand understanding what is going on in the figure. After the equation (4.50) it says "It is customary to introduce the principal quantum number, ##n##, which simply orders the allowed energies, starting with 1 for the ground state. (see the figure)" I still don't understand the figure :( Here is...
Thread 'Understanding how to "tack on" the time wiggle factor'
The last problem I posted on QM made it into advanced homework help, that is why I am putting it here. I am sorry for any hassle imposed on the moderators by myself. Part (a) is quite easy. We get $$\sigma_1 = 2\lambda, \mathbf{v}_1 = \begin{pmatrix} 0 \\ 0 \\ 1 \end{pmatrix} \sigma_2 = \lambda, \mathbf{v}_2 = \begin{pmatrix} 1/\sqrt{2} \\ 1/\sqrt{2} \\ 0 \end{pmatrix} \sigma_3 = -\lambda, \mathbf{v}_3 = \begin{pmatrix} 1/\sqrt{2} \\ -1/\sqrt{2} \\ 0 \end{pmatrix} $$ There are two ways...
