Hey, I'm an Electrical and Computer Engineering senior, studying at the American University of Beirut, one of the top schools in the region. I have recently realized that I really want to go to graduate school and study theoretical computer science, however, due to a general lack of motivation...

Homework Statement Use appropriate substitution to solve the differential equation y'/y + lny = sqrt(1-e^x) Homework Equations The Attempt at a Solution I thought of trying to substitute y=ux but didn't get any helpful results, any help or hints would be great.

TEC stands for Thevenin Equivalent Circuit, and the capacitor does not undergo mutual inductance, so I use its phasor form to find the equivalent thevenin resistance like I would with a resistor.

Homework Statement Derive TEC between terminals "ab". Homework Equations The Attempt at a Solution I figured I'd add the mutual inductances to the inductors, and solve it as a normal RLC circuit, since no current is passing through the 80j coil, it's inductance wouldn't change...

Homework Statement All the inductances in Figure P8.2.10 are j10, all the resistances are 10, and all the capacitances are -j12 . Determine the impedance between terminals 'ab'. Ans. 27 + j9 Homework Equations The Attempt at a Solution I figured I should add up the impedances...

Homework Statement A 2-kg block is attached to a horizonal ideal spring with a spring constant of 200N/m. When the spring has its equilibrium length the block is given a speed of 5m/s. What is the maximum elongation of the spring. Homework Equations Conservation of mechanical energy...

Hello, I am required to write a feasibility study for my Technical English course about a project that could be done in my field of study, I'm an Electrical and Computer Engineering major and I thought of the idea of converting the heat produced by friction of chalk on classroom boards, feet...

Okay, I've been solving problems and I'm starting to get the hang of it, thank you very much.

It's between a and b in both circuits. Can you explain how to find out which are in series and which are in parallel?

I know that definition but how can I apply it in the circuits attached above? Could you identify the series and parallel connections in those circuits and show the logic followed in that identification?

Homework Statement I'm having a bit of a problem identifying series and parallel connections of resistors in some new circuits I've been exposed to, like the ones posted below. I'd be very grateful if anyone could give me some pointers or tips, or perhaps link me to some videos/explanations...

Homework Statement Given an electric field ε V/m that is constant in the x-direction and a charge +q C located at the origin and free to move in the x-direction. (a) What is the magnitude and direction of the force F acting on q? (b) If q moves under the influence of F a distance d m, how...

I did that, let me show you how far I got. Ug= Uc+Ucoil+Ur Uc= q/C, i=-dq/dt, thus q=-∫i.dt=(Im/2∏ft)cos(2∏ft-∅) Ucoil= Ldi/dt = L2∏ftcos(2∏ft-∅) Ur= Ri= Rsin(2∏ft-∅) Umsin(2∏ft)=(Im/2∏ft)cos(2∏ft-∅) + L2∏ftcos(2∏ft-∅) + Rsin(2∏ft-∅) substituting t by 0 yields: (Im/2∏ft)cos(∅) +...

Unfortunately, I don't get my exam back till Friday.

Homework Statement This problem was given in my physics test, and my physics teacher was unable to provide me with an answer for it. Given a circuit made up of a generator of variable frequency, i=Im(sin2∏ft-∅) and voltage u=Um(sin2∏ft), capacitor of capacitance 1μF, resistor of resistance...
