how did you handle people who don't co-operate?
make them owners so that they will be accountable
explain why, communicate the bigger picture of what you're asking them to do, show that what you are doing is in full view of process/not a personal thing but a strategic or tactical problem-solving approach. If thats not effective, contact his/her resource manager/boss and ask to be added to the employee's review process. Then let his/her boss tell that person you hold this power...
Q2: A pnp transistor with its base connected to a voltage source, the V source is connected to a +10V source. The emitter of the transistor is connected to a resistance, and then to the same +10V source. The collector side is connected to a capacitor, which is not charged at t=0-. Given the graph of Vsource = 10 V stepping up at t = 0 to further, draw the graph of Vout. Vout is between the point of collector and capacitor.
