Solve the all parts of given problem:
Problem: A light bulb marked "100 W @ 120 V" is screwed into a socket at one end of a long extension cord, in which each of the two conductors has resistance 0.700 ohms. The other end of the extension cord is plugged into a 120-V outlet.
Part A: Explain why the actual power delivered to the light bulb cannot be 100 W in this situation.
Part B: Draw a circuit diagram.
Part C: Find the actual power delivered to the light bulb in this circuit.
I need help to find the actual power delivered to the light bulb in this circuit.
