As drawn, the negative terminal of the 22uF cap is tied to the positive terminal of the DC voltage source. When an electrolytic cap is reversed biased as this one would be, the insulating oxide layer breaks down and the cap becomes a resistor allowing DC current from the voltage source to flow thru it. This situation typically damages a polarized cap and may cause the cap to fail with a spectacular and messy explosion.
