Answer:
The fuse is a thin wire that is the conductor of electricity is designed to breaks the circuit if there is a fault in an appliance that causes excessive current to flow in a circuit.
The conductor used in the fuse is melt and separated in such cases of excessive current in a circuit and switch the current off.
A circuit breaker is made up of a thin wire that is specially designed to switch that automatically breaks circuit current in the overcurrent condition.
To balance this equation you would do whatever you did I TO one side to the other... so if there is 18 oxygen on the right side then there must be 18 on the left. So 18/2 equals 9... the. You equation will be balanced
