Question: A circuit consists of a 12.0-V battery connected to three resistors (43 ohm, 18 ohm and 110 ohm) in series.
Part I: Find the current that flows through the battery.
Part II: Find the potential difference across the 43 ohm resistor.
Part III: Find the potential difference across the 18 ohm resistor.
Part IV: Find the potential difference across the 110 ohm resistor.
I want you to explain the physics in this question.
