Resistors, capacitors, and inductors are not only classic building blocks of circuits. They inform us about the nature of the properties of resistance, capacitance, and inductance. Even a bare wire has some resistance, some capacitance, and some inductance.
In a DC circuit transient, where you’re modeling a switch opening or closing, a capacitor will resist the change in voltage. This resistance is because the current that is flowing into the capacitor is “filling” the capacitor up, it can’t charge or discharge instantaneously.
Equivalent series resistance (ESR). While we assume the capacitor has no resistance, in reality, there is. This is noticeable when the capacitor is charging and discharging in that some power is being dissipated during the process. It also slows down the speed at which a capacitor can charge and discharge.
The study of resistors, capacitors and inductors allows us to gain a deeper intuition of some of the most important principles that affect the design and operation every circuit. This is because every circuit has resistance, capacitance, and inductance even if they don’t contain resistors, capacitors, or inductors.
An electric field forms across the capacitor. Over time, the positive plate (plate I) accumulates a positive charge from the battery, and the negative plate (plate II) accumulates a negative charge. Eventually, the capacitor holds the maximum charge it can, based on its capacitance and the applied voltage.
If you want to understand how the capacitor works without reading theory and formulas – then build this circuit: You can use a 9V battery, a standard Light-Emitting Diode (LED), and a 1000 µF capacitor. The resistor value can be around 500-1000 ohms. Connect the battery, and you should see the LED turn on. Nothing special yet.
