A camera flash is operated, and a charge of $1.5\,\text{C}$ passes through the flash lamp in $0.0030\,\text{s}$. The mean voltage across the flash lamp is $3600\,\text{V}$. Calculate the electrical energy supplied to the flash lamp and the mean power supplied.
- Aenergy $2400\,\text{J}$, power $7.2\,\text{W}$
- Benergy $2400\,\text{J}$, power $800\,000\,\text{W}$
- Cenergy $5400\,\text{J}$, power $16.2\,\text{W}$
- Denergy $5400\,\text{J}$, power $1.8 \times 10^{6}\,\text{W}$
