Meaning that if there are resistor in parallel with the capacitor, they will be shorted ("eliminated" as you say") the instant after switching. All this behavior of capacitors is based on the relationship between voltage and current in an ideal capacitor, which is Hope this helps.
When capacitors are connected together in parallel, the total or equivalent capacitance, CT, in the circuit is equal to the sum of all the individual capacitors added together. This is because the top plate of capacitor C1 is connected to the top plate of C2, which is connected to the top plate of C3, and so on.
@ADITYAPRAKASH, if the capacitor is initially not charged, and then you connect it across the resistor, you're right. It will momentarily drop the voltage across that resistor to 0. But no, the current will increase. Because now the whole voltage of the source is across the other resistor. and the current when does it resume then ?
When capacitors are connected in parallel, the total capacitance (CT) is the sum of the individual capacitances. This means that the total capacitance is always greater than the value of the largest capacitor in the group.
Because the power source has the same frequency as the series example circuit, and the resistor and capacitor both have the same values of resistance and capacitance, respectively, they must also have the same values of impedance. So, we can begin our analysis table with the same “given” values:
Of course, if you connect two identical capacitors in parallel they will halve their ESD. The only reason to connect a ceramic capacitor in parallel to a electrolytic one, is to make use of its behavior in high frequencies. It would have been best for Ricardo to have supplied an actual representation of the circuit.
