capacitor
For both inductors and capacitors, reactance is inversely proportional to frequency, though, so (Imaginary part of Z)/f is often called "inductance" if it''s positive, or "capacitance" if it''s negative. So your meter is just measuring Z at some specific frequency and labelling -Im(Z)/f as "capacitance". It doesn''t mean you have a negative capacitor.
How to Tell the Polarity of an Electrolytic Capacitor
This means the positive end of the capacitor must be at a higher voltage than the negative one so that charge flows through the circuit from the positive end to negative end. Attaching a capacitor to a circuit in the wrong direction may damage the aluminum oxide material that insulates the capacitor or short circuit itself.
What''s the Difference Between Capacitors and Batteries?
Thus, the conductors in a capacitor develop equal charges with opposite polarity. This also means that an uncharged capacitor does not have any negative or positive terminals – it is only after charging that the polarity of a capacitor is defined. Once a capacitor reaches its capacity to hold a charge, it impedes current flow through a circuit.
