1. The positive terminal of the capacitor is on the side of the sealing. 2. A positive current flows from a positive terminal to negative, right? 3. The first is the positive terminal and the second is the negative terminal. 4. The negative terminal lead is shorter than the positive terminal lead. 5. It develops a negative charge, and is the positive terminal of the battery. 6. A sacrificial iron electrode, also immersed in the solution, is connected to the positive terminal . 7. But doesn't this mean we have a current flowing from a negative terminal to a positive terminal ? 8. The positive terminal looks like a metal cap and the negative terminal looks like a metal disc. 9. The ear connected to the positive terminal hears a louder sound than that connected to the negative. 10. This is usually reversed in button cells, with the flat ended cylindrical can being the positive terminal .
