Two parallel RC circuits in series

In summary, the conversation is about a circuit with two capacitors in series being charged with DC and the question of how the current would flow when discharging the capacitors with C1<<<<C2 and R2<<<<R1 in relation to time. The person asking the question is advised to present a legible diagram and clarify their question before receiving help.

Hi, got a naive question (not in the electronics area)

I have got two capacitors in series when being charged with a DC (I presume the resistors have negligible conductances so I assume the time constant of charging would follow that of a series capacitor circuit), like this,
---||--- (C1) ---||--- (C2)
| |--------| |
---R1--- ---R2----
But how would the current flow when I discharge these capacitors when C1<<<<C2 and R2<<<<R1 in relation to time? and what type of discharging pattern should the time constant follow?

Thanks
And

and_5,

Welcome to PF!

You are going to need to present your circuit in a legible diagram and clarify your question before anyone can help you. Try drawing it and scanning it, or using cad software and taking a screen shot like the one attached.

Related to Two parallel RC circuits in series

1. What is the purpose of connecting two parallel RC circuits in series?

The purpose of connecting two parallel RC circuits in series is to create a more complex circuit that can perform a wider range of functions. By combining two circuits, you can achieve more precise control over the flow of electricity and create more complex waveforms.

2. How do the resistance and capacitance values affect the behavior of the parallel RC circuit?

The resistance and capacitance values determine the time constant of the circuit, which is the time it takes for the capacitor to charge or discharge by 63.2%. A higher resistance value will result in a longer time constant, while a higher capacitance value will result in a shorter time constant.

3. What happens to the overall impedance of the circuit when two parallel RC circuits are connected in series?

The overall impedance of the circuit decreases when two parallel RC circuits are connected in series. This is because the two circuits are essentially working together, and the total resistance is reduced. The decrease in impedance allows for greater current flow.

4. Can two parallel RC circuits in series be used to create a band-pass filter?

Yes, two parallel RC circuits in series can be used to create a band-pass filter. By carefully choosing the resistance and capacitance values, the circuit can allow a specific range of frequencies to pass through while blocking others. This is useful in applications such as audio processing and telecommunications.

5. What are some common applications for two parallel RC circuits in series?

Two parallel RC circuits in series are commonly used in electronic devices such as filters, oscillators, and timers. They are also used in audio processing, telecommunications, and power supply circuits. Additionally, they can be used in scientific and medical equipment for signal processing and control.
