The relation AV(t) AVO0)e T says that the voltage drops asymptotically to zero as t oo. We might ask the question: how long do we have to wait until the voltage across the capacitor AV (t) is zero? but the answer will be After an infinite time. Initially, how large is After an AV(0) AV (t) AV(t) infinitely long time, what is the value of ?121 Saying that the time t for to be zero AV(0) AV(0) will be t oo is always true but doesnt allow us to see the fact that some voltage decays are very fast and others are slower. We can characterize the rate of voltage decay by saying how long we have to wait for AV(t) to become a certain fraction of its initial value. To pursue this, we need to recall that, AV(t) e T AV(0)

    The questions I need help with are in bold [Resistance-Capacitance] = [Resistance] middot [Capacitance] = volta/amp middot coulomb/volt = coulomb/volt = change/change/time = time. Thus, the dimensions of RC are the dimensions of time. Since RC is also a constant, tau = RC is called the 'time constant' of the circuit.) This constant is an important one: it controls the rate of discharge of the capacitor (through the resistor). Because delta V(0) = RI, the voltage across the capacitor is...

  • A 3300 microF capacitor is connected in series with a 50 kilo ohms resistor to a 64 V voltage source. At t=0, the charge on the capacitor is zero.

    1)A 3300 F capacitor is connected in series with a 50 k resistor to a 64 V voltage source. At t=0, the charge on the capacitor is zero.  Initially,  is almost zero, while  is almost 64 V.  The current is constant over time.  While the voltage  across the capacitor changes, the voltage  across the resistor remains constant.  The voltage  across the capacitor is always 64 V.  Initially,  is almost 64 V, while  is almost zero.  As the charge on the capacitor increases over time, so does the current through the circuit.2)At what time is the...
