Solve the all parts of given question:
Question: A 100-m-long copper wire of radius 0.21 mm is connected across a 1.5-V battery. Assume the resistivity of copper is 1.7 x 10-8 Omega•m.
Part I: Determine the resistance of the wire.
Part II: Determine the current through the resistor.
Part III: Determine the power delivered by the battery.
I need help to find the power delivered by the battery.
