Question
In parallel combination of resistances:

  • P.D. is same across each resistance

  • Total resistance is increased

  • Current is same in each resistance

  • All of the above are true

✓

Answer

In parallel combination of resistances, P.D. is same across each resistance.

Hint: In parallel combination, the ends of each resistor are connected to the ends of the same source of potential. Thus, the potential difference across each resistance is same and is equal to the potential difference across the terminals of the source (or battery).
