Question

In a direct current arc welding process, the power source has an open circuit voltage of $100\: V$ and short circuit current of $1000 \:A$. Assume a linear relationship between voltage and current. The arc voltage $(V)$ varies with the arc length $(l)$ as $V=10 + 5l$, where $V$ is in volts and $l$ is in $\text{mm}$. The maximum available arc power during the process is ________________ $\text{kVA}$ (in integer).
