I have bought a bathtub toy which has a water pump in it and it stopped working on the first day.
I thought pump has died so I took it apart to see which model should I order online.
After a month I got it and replaced the faulty one.
But this new pump also was not working so problem was elsewhere.
I took it completly apart and found capacitor in series.
I have never seen that in DC circuit. Any idea why the cap is there?
The whole circuit is battery, capacitor, switch and 5v dc pump in series.
