A leaky 100 microfarad capacitor is charged to a potental difference

  1. Sep 2, 2004 #1
    A leaky 100 microfarad capacitor is cahrged to a potental difference of 50V. IT leaks as though a Kilo ohm is connected across it.

    a) Find the initial discharge current.
    b) If a child can feel an electric shock when the voltage of a source is higherthan 20 V. after what time can the child touch the terminals of the capacitor, without feeling any electric shock.



    Please HElp Me
    very Urgent
    Thanks in advance

    The current through a resistance can be found with Ohm's law: V = IR.

    The current is also the rate of passage of charge (I = dQ/dt), and the voltage on a capacitor is related to its charge by Q = CV. You can easily solve for the voltage on the capacitor at any time.
