Final answer:
The electric power delivered by a current source is calculated using the formula P = IV. Without knowing the voltage, you cannot complete the calculation, but if you know both current and voltage, multiply them to find the power in watts.
Step-by-step explanation:
To calculate the electric power delivered by a current source in a circuit, you can use the formula P = IV, where P is the power in watts, I is the current in amperes, and V is the voltage in volts.
Based on the information provided, the formula implies that we would need the voltage of the battery to accurately calculate the power using the current of 0.2 amperes that the student mentions.
Assuming the voltage is provided in the circuit information, you can multiply it by 0.2 A to find the power delivered by the current source.
For example, if the voltage is 12.0 V, the power delivered by the current source would be calculated as P = (0.2 A)(12.0 V), which equals 2.4 W.
