The correct answer is: The fuse in an electric circuit is connected in series with live.
A fuse is a safety device that is used to protect an electric circuit from damage caused by an overload or short circuit. It is a small, cylindrical device that contains a metal strip that melts when the current flowing through it exceeds a certain value. This melting of the metal strip interrupts the flow of current and protects the circuit from damage.
The fuse is connected in series with the live wire of the circuit. This means that the current flowing through the fuse is the same as the current flowing through the rest of the circuit. If there is an overload or short circuit, the fuse will melt and interrupt the flow of current, protecting the rest of the circuit from damage.
The other options are incorrect because they do not provide the same level of protection for the circuit. If the fuse were connected in parallel with the live wire, the current would still flow through the circuit even if the fuse melted. This would allow the overload or short circuit to continue, which could damage the circuit. If the fuse were connected in parallel with the neutral wire, the current would not flow through the fuse at all. This would mean that the fuse would not provide any protection for the circuit.
