An electrical appliance runs from a mains supply. During normal operation, the appliance takes a current of $3\,\text{A}$, although this current momentarily increases to $4\,\text{A}$ when the appliance is first switched on. The cable connected to the appliance is made to handle currents of up to $6\,\text{A}$. A fuse is fitted to protect the circuit. What rating should the fuse have?
- A$1\,\text{A}$
- B$3\,\text{A}$
- C$5\,\text{A}$
- D$13\,\text{A}$
