What is capacitive loading? (Intuitive understanding)

What does it mean when one says,"It is a capacitive load" and what should I understand (intuitively) when one says so? Question 2: It would be great if one can also add on "why output impedance should be low for capacitive loads." ... It means the load behaves like a capacitor. You have to deliver charge to it before the voltage across it will ...

Polarized Capacitor: Function and Applications

A non-polarized ("non-polar") capacitor is one that has no implicit polarity and can be used in either direction in a circuit. A polarized ("polar") capacitor has an inherent polarity, meaning it may only be connected in one direction in a circuit. What Does It Mean When a Capacitor Is Polarized?

What does J signify on a capacitor?

On a capacitor, J usually signifies that it has a 5% tolerance: - Image from here. So, when the capacitor marking is 2.2 J 250 it usually means 2.2 μF rated with a 5% tolerance capable of withstanding up to 250 volts. To be clear about whether the 250 volts is DC or AC depends on knowledge of the capacitor type.

Is there a physical explanation for why increasing a capacitor''s ...

A larger capacitor has more energy stored in it for a given voltage than a smaller capacitor does. Adding resistance to the circuit decreases the amount of current that flows through it. Both of these effects act to reduce the rate at which the capacitor''s stored energy is dissipated, which increases the value of the circuit''s time constant.

Understanding & Selecting Capacitors

With this being said, that means that a 40 µF capacitor can rate from 37.6 to 42.4 µF and still be considered a passing capacitor. When engineers design motors, they take into consideration this type of tolerance range. They specify the nominal (40 µF) rating along with a tolerance (+/-6%) to make sure that if the capacitor is to be replaced ...
