Answer

Explanation:

Step1: Calculate minimum carbon weight

The minimum carbon - content is $0.15%=0.0015$. Multiply by the weight of steel. $250\times0.0015 = 0.375$

Step2: Round to 2 decimal places

Rounding $0.375$ to 2 decimal places gives $0.38$.

Step3: Calculate maximum carbon weight

The maximum carbon - content is $0.25% = 0.0025$. Multiply by the weight of steel. $250\times0.0025=0.625$

Step4: Round to 2 decimal places

Rounding $0.625$ to 2 decimal places gives $0.63$.

Step5: Calculate current during overload

The fuse's rated current is 30 amperes and the overload is 8% or 0.08. First find the amount of overload current. $30\times0.08 = 2.4$

Step6: Find total current during overload

Add the overload current to the rated current. $30 + 2.4=32.4$

Answer:

a. $0.38$ kilograms b. $0.63$ kilograms 77. $32.4$ amperes
