Power: Practice Problem & Solution

Solution Explained:

To solve this problem, we apply the core principles of Power. Understanding the underlying formula is key to arriving at the correct answer below:

Energy is given by $E = P \times t$. Here, power $P = 100\text{ kW} = 10^5\text{ W}$ and time $t = 1\text{ hour} = 3600\text{ s}$. Thus, $E = 10^5 \times 3600 = 3.6 \times 10^8\text{ J} = 36 \times 10^7\text{ J}$.
