Which of the following are not essential parts of a circuit?

conducting wires
fuse
source of electric potential

Answer 1

-- the FUSE is not essential, but it's a good idea for safety and protection

-- the conducting wires and the source of electric potential are essential parts of a circuit; if you're missing either one of these, you have no circuit
