Question

 Study the circuit shown in which two resistors X and Y of resistances 3 Ω and 6 Ω respectively are joined in series with a battery of 2V.

In which combination of resistors will the (i) potential difference across X and Y and (ii) current through X and Y, be the same

Hint:

In a series circuit, the current remains the same throughout, but in a parallel circuit, the potential difference across each component is identical.

Answer 1

- In a F₂parallel combinationF₂, the F₂potential differenceF₂ across each resistor is the same. Therefore, the potential difference across X and Y will be the same in parallel.
- However, in F₂series combinationF₂, the current through both resistors will be the same as the same current flows through all components in a series circuit.
Thus, the correct combination is the F₂parallel combinationF₂ for the potential difference and the F₂series combinationF₂ for the current.
