Capacitor is considered a short circuit

If a circuit contains nothing but a voltage source in parallel with a group of capacitors, the voltage will be the same across all of the capacitors, just as it is in a resistive parallel circuit. If the circuit instead consists of multiple capacitors that are in series with a voltage source, as shown in Figure 8.2.11, the voltage will divide between them in inverse …

Introduction to Capacitors, Capacitance and Charge

When used on DC supplies a capacitor has infinite impedance (open-circuit), at very high frequencies a capacitor has zero impedance (short-circuit). All capacitors have a maximum working DC voltage rating, (WVDC) so it is advisable to select a capacitor with a voltage rating at least 50% more than the supply voltage.

How to check SMD capacitor for being shorted, without …

A short indicates that one or more of the devices on the circuit have failed short - not necessarily the capacitor. The most common failure mechanism for ceramic capacitors to fail short is mechanical stress causing the ceramic layers to crack and internally short out.

I can''t think of an instance where it would be part of the design, so just make sure it''s not the capacitor, or the capacitance of the circuit, fooling you. Measure the actual resistance across the capacitor (in-circuit), instead of using the continuity tester, and see if the resistance increases with time -- if the resistance goes up, that was the …
