The following resistors are in parallel across a voltage source: 220Ω , 470Ω , and 560Ω . The resistor with the least current is______________?

Correct answer: C. 560 Ω

  • A. 220 Ω
  • B. 470 Ω
  • C. 560 Ω
  • D. impossible to determine without knowing the voltage

Explanation

All parallel resistors have the same voltage across them, so current is inversely proportional to resistance. Therefore, the 560 Ω resistor carries the least current.
