| CURRENT - TYPES OF | ||
We commonly refer to two (2) types of current: DC and AC. One example of DC current at work is a flashlight circuit, where the batteries convert chemical energy into electrical energy. Keeping in mind that current is caused by an imbalance between electric charges, batteries are filled with a chemical called an electrolyte fluid and built using two different types of metal. These metal ends (or terminals) of the battery have different electrical properties; one is positive and the other negative. If the two terminals are connected together, electrons flow at a steady rate from the negative to the positive terminal as they attempt to balance the differing electrical charges between them. |
