To calculate the electric energy delivered, we can use the formula for electrical energy:
\[ \text{Energy} = \text{Power} \times \text{Time} \]
First, we need to calculate the power (in watts) delivered by the battery. The power can be calculated using the formula:
\[ \text{Power} = \text{Voltage} \times \text{Current} \]
Given:
- Voltage (V) = 12.0 V
- Current (I) = 0.40 A
Now we calculate the power:
\[ \text{Power} = 12.0 , \text{V} \times 0.40 , \text{A} = 4.8 , \text{W} \]
Next, we can find the energy delivered over 500 seconds. Using the energy formula:
\[ \text{Energy} = \text{Power} \times \text{Time} \]
Substituting the known values:
\[ \text{Energy} = 4.8 , \text{W} \times 500 , \text{s} = 2400 , \text{J} \]
Thus, the electric energy delivered in 500 seconds is 2,400 Joules.
The correct answer is:
2,400 Joules
