A resistor may be used in series charging for current limiting, filtering, or as a signal isolater. Resistors across caps are to discharge them for your safety or equalize voltages across the caps in series filtering circuit.

when we replace the resistor with a capacitor ,the current will flow until the capacitor charge when capacitor will fully charged there is no current through the circuit because now capacitor will act like an open circuit. for more info plz E-mailt me at "zaib.zafar@yahoo.com"
A fractor is a circuit component that has both the function of resistor and capacitor.
A resistor is connected between a voltage source and a capacitor, charging the capacitor slowly over a time. The actual time depends on the resistance value of the resistor and the capacitance value of the capacitor. Together they produce something that is described as their "time constant value". The 555 measures the capacitor voltage as it increases and compares it to a threshold to trigger things at certain time intervals, and also 555 has a circuit to discharge the capacitor and restart the charging process. By using clever circuit connections, a 555 with a resistor and capacitor can be used to generate pulses, delays, and periodic signals like pulse trains and low-speed clocks for digital circuits.
The resistor allows a slow charge to enter the capacitor. When this charge reaches a certain point the circuit activates and forces the capacitor to discharge. Once discharged the circuit reverses itself and starts the charge over again. The larger the cap and/or resistor the lower the frequency because it takes longer to charge the cap.
because without using capacitor or resistor in a circuit,it cant be complete.Resistor is used to protect the circuit by giving a certain amount of voltage.Capacitor is used to charge and discharge purpose.

I wanna use resistor , capacitor and amplifier 7173 for switch alarm circuit. How can i choice resistor and capacitor value because i wanna use 24V DC.

fully charged.
R for resistor, C for capacitor. RC circuit is a circuit built with a resistor and a capacitor. This circuit will have a typical pulse response that looks like exponential decaying and a typical resonance frequency.
a memristor is the fourth passive element in the electric circuit joining the resistor,inductor and capacitor , the word memristor is the concatenation of "memory" and "resistance"

To add a capacitor and resistor in parallel, simply connect one terminal of the capacitor to one terminal of the resistor, and then connect the other terminal of the capacitor to the other terminal of the resistor. This creates a parallel circuit where both components share the same voltage.
When a capacitor and resistor are connected in parallel in a circuit, the behavior changes in that the capacitor stores and releases electrical energy while the resistor controls the flow of current. This combination can affect the overall impedance and time constant of the circuit, leading to changes in the voltage and current characteristics.
