MCQ
Pick out the correct statement from the following about parallel combination of resistors.
  • A
    The current across the resistors are the same.
  • B
    The resistance offered by all resistors are the same.
  • ✓
    The potential difference is same across each resistor.
  • D
    The equivalent overall resistance is larger than the largest resistor.
✓

Answer

Correct option: C.
The potential difference is same across each resistor.
In parallel combination, the resistors are connected together at one end, and are also all connected together at the other end. So, the potential difference across the resistors will not change and thus, remains the same.
