What is a resistor and a capacitor?
Why do we need a resistor to charge a capacitor? Explanation: When capacitors and resistors are connected together the resistor resists the flow of current that can charge or discharge the capacitor. The larger the resistor, the slower the charge/discharge rate.

Capacitor
Unlike a resistor, an ideal capacitor does not dissipate energy, although real-life capacitors do dissipate a small amount (see Non-ideal behavior). The earliest forms of capacitors were created in the 1740s, when European experimenters discovered that electric charge could be stored in water-filled glass jars that came to be known as Leyden jars .

4.11 DC Circuits Containing Resistors and Capacitors
Discharging a capacitor through a resistor proceeds in a similar fashion, as Figure 2 illustrates. Initially, the current is I o = V o / R, driven by the initial voltage V o on the capacitor. As the voltage decreases, the current and hence the rate of discharge decreases, implying another exponential formula for V .
Capacitor Failures
Open mode failure An open mode failure in a capacitor can have undesirable effects on electronic equipment and components on the circuit. For example, if a large capacitor is used in the smoothing circuit of a power supply, a large wave-like voltage *4 can be converted to a flat DC voltage, but if the capacitor is open, a large voltage wave is directly applied to the circuit, which …

There are a variety of models for a "real" capacitor, and the simplest of those is just an ideal capacitor in series with a small resistor. So, there''s at least a small resistor always present. The size of that small resistor …
A Complete Guide To Resistors: What They Are, The
A resistor is a passive electrical component that creates resistance in a circuit to limit the flow of an electric circuit. A resistor will h A resistor will have a resistance rating which will create a specified volt drop. The resistance level is measured in Ohms, Ohm''s law states that the current is proportional to the voltage and can be found using the equation R = V/I.
