Why is the capacitor short-circuited in this example?
Any element for which terminals are connected by a conductor, as the capacitor in the figure, is said to be shorted. By having their shorted terminals, the voltage thereof is zero (more precisely, the potential difference between them), so that this element is not operational in the circuit, and can be removed for analysis. ...

How to Read a Capacitor: 13 Steps (with Pictures)
Check the voltage rating. If there is room on the body of the capacitor, the manufacturer usually lists voltage as a number followed by a V, VDC, VDCW, or WV (for "Working Voltage"). This is the maximum voltage the capacitor is designed to handle. 1 kV = 1,000 volts. See below if you suspect your capacitor uses a code for voltage (a single …
