I see, thanks a lot.

Well I'm not very knowledgeable in wires and electronics. But all I was given in the problem was that it is a "#6 wire" You know what does that mean? Is that some type of wire nowadays already manufactured with it's own specifications ?

Probably a stupid question, but how do I know the cross section area of wire if I'm not given the radius of the wire?

Homework Statement Find the maximun possible power delivered to the resistor. Given current through a power line. And the length of the loop that will receive the induced emf. Homework Equations B= uo*I/2pi*ρ Vemf= -d/dt ∫B*dS The Attempt at a Solution Here's my attempted solution...

Thanks a lot man. I know it was simple, but got stucked on it for some reason.

Here's a better view of the HW problem. I copied that exact same diagram on PSPICE. Made a Bias point analysis and got these Voltage and Current values. http://postimg.org/image/bcry7ph7l/ Now to solve the problem. I'm not really sure what to do but I used the formula on "Hint". I use...

Homework Statement We have a transistor with RB, RE and A LED being a GaAs Light-emitting Diode (LED with a forward voltage of approximately 1.5V. Values for RB= 2K, Vs-offset=5, Vs-amplitude=4, V-frequency= 1KHz, let β=100 what is the value of the emitter resistor for which the LED...

I have a last question guys, and thanks for the input so far. Can the BJT transistor act as a voltage amplifier? Or does it just amplify current and power?

thanks

I see, thanks a lot, I'll take a look at the file.

About the stages of a transistor.. Active,Saturation and Cutoff. Active its obviously on and cutoff off. May be a dumb question but is the transistor ON on Saturation mode? Also my textbooks says that when the BE junction is forward bias, Vbe= 0.7V. But at the same time in another problem it...

Homework Statement Find the transfer function of an RLC circuilt and the magnitude. (All the impedances are in series) and the Vo is in the R. Vi is the source voltage. Homework Equations The Attempt at a Solution So transfer function of the circuit => Vo/Vi = R/ (sL+1/sC +...
