The negative terminal may be marked with a minus sign (-) or a shorter terminal lead. If there are no markings, you can use a multimeter to test the terminals and determine which one has a higher voltage reading, which would be the positive terminal. 3. Can I use a capacitor with unmarked terminals?
Hopefully fueled by lubrication and not dementia. The marking of capacitor terminals is an antiquated practice that is no longer necessary. This is completely and totally incorrect. Many modern capacitors are polarized and failure to recognize this can be disastrous. To the OP: Your capacitor is clearly marked 250 VAC.
The charge quantity stored by a capacitor with a given terminal voltage is its capacitance. The capacitance of a capacitor has a definite relationship to the area of the plates and the thickness of the dielectric. Refer to Figure 1 (a) and recall that electrons are attracted to a positive voltage.
In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, a term still encountered in a few compound names, such as the condenser microphone.
An ideal capacitor is characterized by a constant capacitance C, in farads in the SI system of units, defined as the ratio of the positive or negative charge Q on each conductor to the voltage V between them: A capacitance of one farad (F) means that one coulomb of charge on each conductor causes a voltage of one volt across the device.
The capacitance of a capacitor can change value with the circuit frequency (Hz) y with the ambient temperature. Smaller ceramic capacitors can have a nominal value as low as one pico-Farad, ( 1pF ) while larger electrolytic’s can have a nominal capacitance value of up to one Farad, ( 1F ).
To identify the positive and the negative terminals of a capacitor, you have to look for a minus sign or a large stripe, or both on one of the capacitor''s sides. The negative …

Discrete capacitors deviate from the ideal capacitor. An ideal capacitor only stores and releases electrical energy, with no dissipation. Capacitor components have losses and parasitic inductive parts. These imperfections in material and construction can have positive implications such as linear frequency and temperature behavior in class 1 ceramic capacitors. Conversel…
