With D2 right at the "on/off" threshold, it has 0.7V and 0 current. That means the current through the 1kΩ is 0.7mA And therefore the current through the 4kΩ is 0.7mA So the voltage across the 4 kΩ is 2.8V And Vin would equal 2.8V Am I right? I can do 1 graph for each diode. My...

Homework Statement http://img39.imageshack.us/img39/7496/59187398.th.jpg VDON=0,7 First it is asked to calculate V0 for Vin=-1V and Vin=-5V. Secondly it is asked to draw V0(Vin) for -10<Vin<10 Homework Equations The Attempt at a Solution Using Kirchhoff Volt Law I've...

I have a similar exercise and I'm finding some difficulty in understanding it. So from Gauss' Law I have \epsilon_{0}\oint EdA=q_{enc} I know q_{enc}=\rho\,V=\rho\,y But I don't get where do those "2" come from as in 2EA and 2y. I also fail to understand the difference between the inside...
