Resistance experienced by capacitors in circuit

In summary, the conversation is discussing the resistance experienced by the capacitors in a circuit, and how to calculate the time taken for the capacitor to discharge. The formula V=V_oe^{-\frac{t}{CR}} is mentioned, and there is a question about what R should be in the formula. The conversation also mentions that the two resistances in the circuit are connected in parallel and the formula \frac{1}{R_e}=\frac{1}{R_1}+\frac{1}{R_2} may be applicable. However, it is stated that the two resistances are actually in series. The conversation ends with a clarification that the circuit is indeed in series.

what is the resistance experienced by the capacitors in the circuit (diagram) ?

i am actually supposed calculate the time taken during the discharging of capacitor using this formula -

[tex]V=V_oe^{-\frac{t}{CR}}[/tex]

what should the R there be ?

Since they are connected in parallel , would it be

[tex]\frac{1}{R_e}=\frac{1}{R_1}+\frac{1}{R_2}[/tex] ?

where R=R_e

It is in series. If you bend it in the middle, still it is in series.
 

Related to Resistance experienced by capacitors in circuit

1. What is resistance experienced by capacitors in circuit?

Resistance experienced by capacitors in circuit is the opposition to the flow of electrical current through a capacitor. This resistance is caused by factors such as the material properties of the capacitor, the length and width of its plates, and the dielectric material used.

2. How does resistance affect the performance of capacitors in a circuit?

Resistance can affect the performance of capacitors in a circuit by causing energy losses in the form of heat and reducing the overall efficiency of the circuit. It can also lead to a decrease in the capacitance of the capacitor, resulting in a slower charging and discharging process.

3. What are the factors that contribute to resistance in capacitors?

The main factors that contribute to resistance in capacitors are the type of material used in the capacitor, the length and width of its plates, and the dielectric material. Other factors such as temperature, frequency, and the presence of impurities can also affect the resistance of a capacitor.

4. How can resistance in capacitors be reduced?

Resistance in capacitors can be reduced by using materials with lower resistivity, increasing the surface area of the plates, and using a dielectric material with a higher dielectric strength. Additionally, keeping the temperature and frequency of the circuit stable can also help reduce resistance in capacitors.

5. Can resistance in capacitors be completely eliminated?

No, resistance in capacitors cannot be completely eliminated. However, it can be minimized by using high-quality materials and proper circuit design. In some cases, specialized capacitors, such as supercapacitors, can be used to reduce the effects of resistance in a circuit.
