Total power: $P = 15 \times 40 + 5 \times 100 + 5 \times 80 + 1 \times 1000 = 600 + 500 + 400 + 1000 = 2500\,\text{W}$
Total current: $I = \frac{P}{V} = \frac{2500}{220} \approx 11.36\,\text{A}$
The fuse must safely carry this current. The smallest standard value that is greater than or equal to 11.36 A from the options is 12 A. Answer: A.
Which of the following errors would be detected when a trial balance is extracted?
A trial balance checks whether total debits equal total credits. If different amounts are posted on the debit and credit sides of the same transaction, the totals will not agree and the error will be detected. The other errors — complete omissions, reversed entries, and misclassification between accounts — all maintain the arithmetic equality of debits and credits, so they go undetected by a trial balance.
