Madelyn and Scarlett observed that when the current is momentarily zero, no energy is delivered to the resistor. Madelyn asks Scarlett why this is so.
Which explanation is correct?
a. "Energy is actually being delivered to the resistor, but the amount is too low to register."
b. "The energy delivered to the resistor depends on the current, and when the current is zero, no energy is delivered."
c. "The energy delivered to the resistor depends on the resistance value, which depends on the current. Zero current means zero resistance."
d. "Because of conservation of energy, no energy is delivered to the resistor, whether the current is zero or is some nonzero value.
