Title: Electricity Problem: How are voltage, current, and resistance
... Electrically charged particles exert forces on each other. There are two types of charges: negative and positive. Atoms are made up of particles that carry these different types of charges. Within an atom, electrons are negatively charged, and protons are positively charged. Other particles called n ...
