Question

In a circuit two or more resistors are connected in parallel. Then the following quantity is same for all the resistors

• A. Potential difference
• B. Electric current
• C. Resistance
• D. Heat

Answer 1

The Correct Option is A

To solve the problem, we need to determine which physical quantity remains the same for all resistors connected in a parallel circuit.

1. Understanding Parallel Connection:
In a parallel circuit, each resistor is connected directly across the same two points of the circuit. This means that each resistor experiences the same voltage across its terminals.

2. Analyzing the Quantities:

- Potential difference: Same across all resistors in parallel. ✅
- Electric current: Divides inversely according to the resistance values.
- Resistance: May vary between resistors.
- Heat: Depends on both current and resistance, so it varies.

Final Answer:
The quantity that remains the same for all resistors in parallel is $ \text{Potential difference} $
