No, adding capacitors does not increase the current if you have a dc supply and the load is constant. However, you may increase the transient current when the load is first connected or if the load current changes suddenly.
To increase the charge in a capacitor, increase the value of the capacitor. For instance, increasing the value of the capacitor from 5 nanofarads to 5 microfarads: C = 5 microfarads = 0.000015 farads = 5 x 10^-6. The time constant (RC) is calculated as RC = (300) (5 x 10^-6) = 0.0015 or 1,500 microseconds. The current (I) through the capacitor can be calculated as I (t) = 120/300 * e^-3/1500 = 0.4 (e^-0.002) = (0.4) (0.998) = 0.3992.
Capacitors influence the current in a circuit by having a direct relationship with it. In an AC circuit, increasing the capacitance increases the AC current. Diodes, however, are used to convert AC current into DC current, resulting in an increase in DC current. Connect a capacitor in series with a resistor in your circuit, similar to an RC circuit.
Off cource you can get more current from a bigger capacitor, but after this you have "something" to replenish with the same power or energy. Btw the formula that you mention is valid for a charging up to 63% and not for 99% Unfortunately, a lot of information on eHow is of very low quality.
Capacitors react against changes in voltage by supplying or drawing current in the direction necessary to oppose the change. When a capacitor is faced with an increasing voltage, it acts as a load: drawing current as it absorbs energy (current going in the negative side and out the positive side, like a resistor).
Given a fixed voltage, the capacitor current is zero and thus the capacitor behaves like an open. If the voltage is changing rapidly, the current will be high and the capacitor behaves more like a short. Expressed as a formula: i = Cdv dt (8.2.5) (8.2.5) i = C d v d t Where i i is the current flowing through the capacitor, C C is the capacitance,
A larger capacitor has more energy stored in it for a given voltage than a smaller capacitor does. Adding resistance to the circuit decreases the amount of current that flows through it. Both of these effects act to reduce the rate at which the capacitor's stored energy is dissipated, which increases the value of the circuit's time constant.

In general, adding capacitors across the bridge would typically reduce current spikes. However, adding capacitors may introduce a non-linearity in your circuit which may introduce stability problems, but not "spikes".
Capacitors store energy in the form of an electric field. At its most simple, a capacitor can be little more than a pair of metal plates separated by air. As this constitutes an open circuit, DC current will not flow through a capacitor.
