A circuit-breaker is made to safeguard a circuit that normally carries a current of $2\,\text{A}$. The time needed to open the circuit depends on the current, as shown in the graph. What occurs when the current in the circuit is $2\,\text{A}$, and what occurs when the current is $18\,\text{A}$?
- Athe circuit breaks in less than $0.01\,\text{s}$; the circuit breaks in less than $0.01\,\text{s}$
- Bthe circuit breaks in less than $0.01\,\text{s}$; the circuit does not break
- Cthe circuit does not break; the circuit breaks in less than $0.01\,\text{s}$
- Dthe circuit does not break; the circuit does not break
