Hi, this is the question: For part a) I did V=(L/C)-1/2=2.5x108 m/s. And then I said T=x/v where x=10m, so T=4x10-8s. For part b) V++V-=VL...since it's the first wave I suppose there wouldn't be a reflecting wave yet, so V-=0. I have an equation that says V+=[VL/2](1+R0/RL)...since it is an open circuit, RL=infinity, so R0/RL=0, and the equation becomes V+=VL/2 and VL=12V, so V+=pulse height = 6V.....but if [tex]V_-=0[/tex] then according to my first equation [tex]V_+=V_L=12V[/tex]..I'm confused. I have a feeling b) is wrong and that it should actually be 24V because of a combination of waves, I'm not sure about part a), any help please?
