 · What is the difference between an open and a closed circuit? (Answer: A closed circuit is a circuit with a complete path, which allows charge to flow [current]. An open circuit is a circuit with a break in the path, and thus, charge is unable to move.) What is voltage? (Answer: The difference in electrical potential between two points in a circuit. You can think of voltage as the "electrical ...
