That's exactly what i was looking for! Thank you! I solved it without zener, but used diode and a voltage source instead, hopefully it's correct! Thanks again!

you can use diodes, voltage sources, and resistors. i don't know how to get Vo=3 if Vi=4 and Vo=-3 if Vi=4 in one circuit!

i want to design a diode circuit where the Vo vs. Vi looks like this: Vi between -2 and 2 Vo = Vi Vi between 2 and 4 Vo is a linear with slope 0.5 Vi between -2 and -4 Vo is a linear with slope 0.5 Vi>4 Vo=3 Vi<4 Vo=-3 how can i do this?

Well the problem is not about this sum, if you find a series like the one described the problem will be solved. i have submitted the following answer: 2+4+8+16+32+64+...+2^k = 2(1+2+4+8+...+2^(k-1) = 2(2^k -1)/2-1 = 2(2^k -1) but 2^k = n k = log (base 2) n right, then substitute in the...

yeah, i should've added more restrictions. well the numbers must increase as we go on, for example: 1+2+3+...+n=n(n+1)/2 right, but this is of second order i want to add numbers that increase up to n, and their sum is of order 1.

no, i need the last number to be n. some how i need to find a set of numbers when added together all i get is a multiple of the last number.

i need to find a series of numbers up to n that will add up to kn x1 + x2 + x3+ ... + n = kn where k is a constant. this is part of a long complex problem once this sum is found it will finally be solved.

hello, i designed a project and i finished it my final step is i want the user to enter 3 bits if it was 000 i will do the first choice, which has 4 inputs and 14 outputs displayed on the 2 digit 7 segment dispaly if it was 001 i will do the second choice, which has 5 inputs and 7 outputs...

i'm trying to solve the problem by finding the integral factor by inspection: 1) y(2 - 3xy)dx - xdy =0 2) y(x^2+y^2-1)dx + x(x^2+y^2+1)dy=0 i can't solve those two questions! Help please. Thanks in advance

Oh OK! Got it, Thanks

Thanks, but what is its value? is it V=Kq\r1 through r1<r<r2 or is it V=kq/r2 because if i considered the potential being the integral from a to b for E.dl where b is at infinity so Vb wil be zero then i will get Va: a) at distance r1 it will be Kq/r1 b) at distance r2 it will be k(q+Q)/r2...

Homework Statement its not a statement but i was wondering: I'm studying the electric potential and when we have a sphere with inner radious r1 and outer radious r2 that has a charge let's say +Q with a cavity and there is a point charge q inside this cavity so the inner surface will have -q...
