The resistor results in a voltage drop and heat dissipation. It means that the capacitor is not the perfect capacitor many of us might expect it to be. In a good capacitor the ESR is very small, and in a poor capacitor the ESR is large. What is the effect of ESR?
This voltage will be the product of the current and the ESR of the capacitor plus a negligible voltage due to the small charge in the capacitor. Since the current is known, the ESR value is calculated by dividing the measured voltage by the current. The results are then displayed on the meter readout.

Energy Loss: The ESR dissipates energy in the form of heat due to the resistance in series with the capacitor. In switching power supplies, where efficiency is crucial, any power loss is undesirable. A high ESR can result in higher heat dissipation, which reduces the overall efficiency of the power supply.
