Answer 1

Answer:

1. First, and most commonly, when too many lights or plug-in appliances draw power from the circuit, it can overload the capacity of the fuse and cause the metal ribbon inside the fuse to melt through. The result is that all lights, outlets, and appliances powered by the circuit will go dead suddenly
2. when switch is open then charges suddenly stops flowing .as same as like when bus driver suddenly stopes the bus peoples get collapsed for some time .same thing happen withs electrons and since electrons did not like each other they get distributed in conductor so they can get less repullsion
