1. Solar batteries were removed, power supply became exchangeable – one galvanic cell, size AA.

2. Electromotive force measurements of a galvanic cell were carried out by means of a glass electrode.

3. 28 The metal with a lower potential in the galvanic cell will be anodic and will corrode.

4. The galvanic cell and the process of galvanization were both named for Luigi Galvani, and his discoveries paved the way for electrical batteries, galvanization, and cathodic protection.
