How To Determine The Polarity Of A Capacitor. Many recent capacitors are marked with the actual and - signs and this makes it easy to determine the polarity of the capacitor. Depending on how you intend to use it in a circuit a capacitor can either be rectangular tubular.
Answer 1 of 2. I Approached the problem as follows. Aug 5 2010.
Make sure you pay close attention to the capacitor positive side and negative side such that you dont damage it or the rest of the circuit.
If nothing at all all you can do is guess. Make sure you pay close attention to the capacitor positive side and negative side such that you dont damage it or the rest of the circuit. Certain capacitors have variation in the height of the terminals. After full charge read the readings.
