Final answer:
To calculate the power produced by the battery in the circuit, use the equation P = IV. With a current of 1 Amp and a voltage of 9 Volts, the power produced is 9 watts.
Step-by-step explanation:
The student's question involves determining the power produced by a battery in a simple circuit, using a 9 V battery and a 9 Ohm lightbulb with a current of 1 Amp. To find the power, we can use the equation P = IV, where P is the power in watts, I is the current in amperes, and V is the voltage in volts.
Given that I = 1 A and V = 9 V, we can calculate the power as:
P = I × V
P = 1 A × 9 V
P = 9 W
So, the power produced by the battery is 9 watts.
