Ripple Current Effects on Capacitors Performance | doEEEt
For low-voltage circuits that operate at high currents such as some modern CPUs, the demand for very low ESRs is even higher. Low equivalent series resistance enables capacitors to withstand high ripple currents. In comparison, capacitors with high ESR ratings dissipate more heat, and are unsuitable for high ripple current environments.
Ripple voltage filtering capacitor
This ignores the load, which will drain current from the regularly-topped-up capacitor and cause the voltage to fall. Choosing the capacitor size and the supplied current through the bridge rectifier for a known load current leads to a known ripple voltage across the capacitor.

How does a capacitor resist changes in voltage?
Let the tank have a input and output pipe. If pressure instantaneously increases the tank cannot fill instantaneously so current will flow through output pipe. If pressure increases slowly the tank has time to fill as well. This explains low impedance of capacitor for low frequency (slow change) and high impedance for high frequency (fast …

A licensed HVAC professional will come with a multimeter to test the voltage rating across the capacitor terminals. Because the capacitor stores energy that it releases to help the motor start, it has to be set to s specific microfarad rating. If the voltage reading is too low, the capacitor is likely defective and needs replacing.

Why does capacitance affect the charging time of a capacitor?
Second what makes a capacitor "bigger" (in the sense of more capacity). If you take an electron away from a positive charge, it develops a voltage. The more the charges are separated, the higher the voltage is. So the voltage per charge of a capacitor goes up as the plates get more separate*, and the capacitance goes down.
