When a camera flash is operated, a charge of $1.5\,\text{C}$ passes through the flash-tube in $0.0030\,\text{s}$. The average potential difference across the flash-tube is $3600\,\text{V}$. Calculate the electrical energy delivered to the flash-tube and the average power delivered.
- A$2400\,\text{J}$ and $7.2\,\text{W}$
- B$2400\,\text{J}$ and $800\,000\,\text{W}$
- C$5400\,\text{J}$ and $16.2\,\text{W}$
- D$5400\,\text{J}$ and $1.8 \times 10^{6}\,\text{W}$
