QUESTIONS: 1. A circuit breaker is a fire-safety device that cuts off a household circuit if the current in that circuit exceeds a maximum safe level. Each appliance/light etc., on a circuit can be considered to be an additional resistor. a) Are household circuits wired in series or parallel? Cite one observation (not "calculation," not "formula") you can make about a household circuit that supports your answer. b) In terms of the way that additional resistors affect the type of circuit you identified in "a," explain why engaging additional resistors in this type of circuit increases the risk of fire. 2. Assume you turn on enough devices on a circuit to run a current of 10 A, and leave it that way for 24 hours. Calculate the number of electrons that will pass a point in this circuit over those 24 hours
