Hey! I'm not sure where this goes but it has to do more with math than electrical. To start things off, we were given Voltage (10v) and a resistor source (100ohms). This had to be done in excel, where we would enter the formula for 11 values and excel would calculate the answers. Then we graph Current and Load voltage, ect. This is what I got, http://img515.imageshack.us/img515/7241/untitledjb8.jpg Heres the question: Where does the plot intersect the vertical axis? If extended, where would it intersect, the horitzontal axis? Either I'm making to much of this question or I did something wrong. Now, I know the vertical axis goes up and down (Y) and the horitzontal axis goes from left to right (x). So basically, it touches 40-100 and 0-6? Thanks for any help.
