WBCS.LIVE practice question

Which quantity remains constant in parallel connection of resistance?

Solve this multiple-choice question and check the correct answer with its explanation below.

Answer options

  1. Electric current flow rate
  2. Potential difference
  3. Amount of electricity
  4. Both the potential difference and amount of electricity

Correct answer and explanation

Correct answer: Potential difference

Explanation: āœ… Correct Answer: B) Potential difference šŸ“š Explanation: In a parallel connection of resistors, the "Potential difference" (Voltage) across each individual branch remains exactly the same. This is a fundamental rule of electrical circuits. While the total current splits between the different paths based on their resistance, the electrical pressure remains constant. This is why all appliances in our homes are connected in parallel.
