A student sets up two circuits: circuit X uses a thin, long copper wire, and circuit Y uses a thick, short copper wire, both connected to identical batteries. Which circuit will have higher resistance, and why?

Subject: General Awareness | Topic: Science | Difficulty: MEDIUM

Options

1. (A) Circuit Y, because resistance increases with length and decreases with cross-sectional area
2. (B) Circuit X, because resistance decreases with length and increases with cross-sectional area
3. (C) Circuit X, because resistance increases with length and decreases with cross-sectional area
4. (D) Circuit Y, because resistance decreases with length and increases with cross-sectional area

Verified Answer

Option (C): Circuit X, because resistance increases with length and decreases with cross-sectional area
