    How Long to Charge a 470µF Capacitor to 330V with a 3V Battery?

    Well, Q = CV Q= 10*10^-6*3V Q=30µC i = dq/dt t= 30*10^-6/10*10^-6 Is it true? Wc= 0.5*C*V^2 Wc= 0.5*10*10^-6*(3^2) Wc= 4.5 × 10-5µJ Is it true? I'm not really sure about my answers...

    How Long to Charge a 470µF Capacitor to 330V with a 3V Battery?

    A capacitor is used in the electronic flash unit of a camera. A battery with a constant voltage of 3V is used to charge the capacitor to 330V at 10µA. How long does it take to charge the capacitor when C=470µF ? What is the stored energy ? What is the current delivered by the battery?

    I think I'm going to fail Signals and Systems?

    Hi friends, I'm new in this forum and very happy to be here. I need your guidance on what to do with my Signals and Systems course which I expect to turn into a failure. I'm studying Electronics Engineering and I think I'm going to fail Signals and Systems because I got 9 out of 100 on my first...
