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 parallel combination, the potential difference across each resistor is identical. Consequently, the potential difference across X and Y will be equal in parallel.
- Conversely, in a series combination, the current through both resistors is the same, as the same current traverses all components in a series circuit.
Therefore, the appropriate combination is the parallel combination for potential difference and the series combination for current.
