Problem Analysis:
We need to calculate the heat generated when a specific amount of charge moves across a given potential difference. The key quantities provided are:
The heat generated (which is equivalent to the electrical energy transferred) when a charge \(Q\) moves through a potential difference \(V\) is given by the formula:
\(H = Q \times V\)
Where:
Substitute the given values into the formula:
\(H = 96000 \text{ C} \times 50 \text{ V}\)
Perform the multiplication:
\(H = 4,800,000 \text{ J}\)
Express the answer in scientific notation:
To match the format of the options, we convert 4,800,000 J to scientific notation:
\(H = 4.8 \times 10^6 \text{ J}\)
The calculated heat generated is \(4.8 \times 10^6\) J. This matches one of the provided options.
