Answer 1

1. Fuse symbol is a rectangle with the term 'fuse' written in it. 2. Energy Transferred = \(13C \times 230V= 2990 J\) 3. The current is calculated by utilizing the formula \(I = \frac{Q}{T}\) 4. Hence, Current required to melt the fuse wire = \(I= \frac{1.52C}{0.40sec} = 3.8A\)

Answer 2

## Step1: The first question asked is to identify the correct symbol for a fuse. Since symbols are not provided in multiple choices style, hence the answer would just be known by one understanding electric circuit symbols. Usually, a fuse is symbolized as a rectangular box with the 'fuse' word written in it. ## Step2: The second question demand you to compute the energy transferred when 13C of charge flows through an appliance. To calculate this computation, we will apply the formula: ### **\(Energy\,Transfer = Current Flow \times Potential Difference\)** ## Step3: Then, subsume its values representing 13C (= Charge Flow) and 230V (=Potential Difference). ### **\(Energy\,Transfer = 13C \times 230V\)** ## Step 4 : After performing arithmetic calculations, we obtain the desired energy transfer in the electrical appliance. ## Step 5: The next question asks for the correlation between the charge flow (Q), current (I), and time (T). Again, this is stated according to the circuit rules[integrating here we are expected ### **\(I = \frac{Q}{T}\)** ## Step 6: In the final part of the problem, you are asked to reckon the current necessary for a fuse wire to melt, given charge flow(1.52C) and time duration (0.40 sec). The computation employs the advertisement formula. ### **\(I = \frac{1.52C}{0.40sec}\)** ## Step7: Perform the arithmetic computations to disclose the compelling results.
