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.
