This item is a short in-class question about distribution of charge over time in an insulation rod. Students are asked to identify a correct response from four diagrams of possible distribution patterns. Inquiry is promoted as there are two responses that may be accurate. This item is part of a larger collection of classroom questions and simulations developed by the Boston University Physics Department.
