Coin Battery






A coin battery is a battery with minimal voltage that is made by putting 2 different coins in a small measuring cup that has different kinds of liquid each. Each type of liquid has different voltages; some are even with very minimal voltages. We used a VOM for measuring the DC voltage. Based on our experiment, the more acidic the liquid is, the higher the voltage it has. The more plane or baser it was, like water, the lesser the voltage. We used coke, water, buko juice, liquid soap, and tap water as the liquid.

    Kindly add your data gathered to the blog so that I could see what you meant about acidity and voltage relationship.

    Why is there a reading without the coin present?
