An ideal capacitor in series with resistance is called Equivalent series resistance of the capacitor. The equivalent series resistance or ESR in a capacitor is the internal resistance that appears in series with the capacitance of the device. Let's see the below symbols, which are representing ESR of the capacitor.

However, if one put a pure resistance in parallel with a pure capacitance (Figure 2a), the ESR of the combination is as illustrated in Figure 2b. From Figure 2a, however, it is obvious that there is no actual series resistance in series with the capacitor.
There are specific ESR meters that are available in the market which can be useful to measure the ESR of a capacitor. These meters use Alternating current, such as square wave in a specific frequency across the capacitor. Based on the change in frequency of the signal the ESR value of the capacitor can be calculated.
The ESR, or Equivalent Series Resistance is an electrical property that refers to the electrical resistance found in series with a capacitor in a circuit. Essentially, it represents the internal resistance of an actual capacitor, which is an inherent characteristic of all capacitors, even those considered to be of high quality.
Personally, and as a general rule and for repairs of medium quality, cheap things, if the capacitor I am going to use has a maximum ESR of twice what it says in the table, I'll take it for granted. The quality of the capacitors in a switched-mode power supply largely determines the quality of the power supply itself.

Without resistance in the circuit, the capacitance charges according to the rate of change of the applied voltage. That means that when the voltage changes the most, the current in the capacitor will be the greatest. When the voltage reaches its maximum value, the current will be zero, but as the voltage decreases, the current changes direction. As the current is already …

Pure capacitors and inductors do not dissipate energy; any component which dissipates energy must be treated in an equivalent circuit model incorporating one or more resistors. Actual passive two-terminal components can be represented by some network of lumped and distributed ideal inductors, capacitors, and resistors, in the sense that the real component behaves as the network does. Some of the components of the equivalent circuit can vary with conditions, e.g., frequenc…
