Question: In a parallel circuit, if one resistor fails open, what happens to the other resistors?

Options:

  1. They stop working
  2. They continue to operate normally
  3. They short circuit
  4. They increase in resistance

Correct Answer: They continue to operate normally

Solution: 

If one resistor in a parallel circuit fails open, the other resistors continue to operate normally as they are still connected to the same voltage source.

Questions & Step-by-Step Solutions

In a parallel circuit, if one resistor fails open, what happens to the other resistors?
  • Step 1: Understand what a parallel circuit is. In a parallel circuit, multiple resistors are connected across the same voltage source.
  • Step 2: Know what happens when a resistor fails open. If a resistor fails open, it means that it is no longer part of the circuit and does not allow current to flow through it.
  • Step 3: Recognize that the other resistors are still connected to the voltage source. Since they are in parallel, they still have the same voltage across them.
  • Step 4: Conclude that the other resistors continue to operate normally. They will still allow current to flow through them, as they are unaffected by the failure of one resistor.
  • Parallel Circuit Behavior – In a parallel circuit, each resistor operates independently, so if one fails, the others remain functional.
