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.
Condenser Connection To measure the ESR of a capacitor, you must first connect the capacitor to the TC-1 meter. Make sure that the capacitor is downloaded before taking the measurement. Click on the analysis button The TC-1 component meter will generate a test signal of a specified frequency, usually in the kilohertz range.
The datasheet of the capacitor does provide the following information about the ESR of the capacitor: At 120 Hz and 20 °C the tan respectively the Dissipation Factor DF is specified with a maximum value of 20% (= worst case). Now we will use the Bode 100 to check if our capacitor does show a similar ESR value.
The measurement of ESL can be done easily by observing the impedance versus frequency plot given by the capacitor manufacturer’s datasheet. The impedance of the capacitor changes when the frequency across the capacitor is changed.
The capacitor under test is placed in series between the center conductor and the ground conductor. The unloaded characteristic of the resonator line must first be determined before carrying out the ESR measurement on the capacitor.
To model the behavior of an actual capacitor requires the addition of extra elements to the capacitor model. ESR is actually the resistance that a capacitor shows in the border between capacitor-like behavior and inductor-like behavior, i.e., resistance at the resonance frequency.

Capacitors, like batteries, have internal resistance, so their output voltage is not an emf unless current is zero. This is difficult to measure in practice so we refer to a capacitor''s voltage rather than its emf. But the source of potential difference in a capacitor is fundamental and it is an emf.

Equivalent series resistance (ESR) is one of the non-ideal characteristics of a capacitor which may cause a variety of performance issues in electronic circuits.
