Sample Physics New PBA Content (2022-23 Scheme): The potentiometer is used to determine the internal resistance of a cell in the lab.
i. What is the principle behind using a potentiometer to measure internal resistance? (01)
ii. Why is the potentiometer preferred for measuring internal resistance of a cell? (01)
iii. Table below shows some values obtained using the null deflection method. Copy and complete the missing entries in the given table. (03)
| No of obs | Resistance R | Length of balance point without R. (l₁) | Length of balance point with R (l₂) | Difference of lengths | Internal resistance r |
|---|---|---|---|---|---|
| Units | (—) | (—) | (—) | (—) | (—) |
| 1 | 3 | 223 | 97 | ||
| 2 | 5 | 236 | 56 | ||
| 3 | 7 | 227 | 31 |
iv. How do you determine the emf of cell using potentiometer? (01)
And so on for other subjects (Chemistry: salt analysis, titration; Biology: catalase, antibiotic test; Computer: Python code, MVP for store).
Preparation Tips for New FBISE Class 12 PBA (2022-23 Scheme)
- Focus on SLO-based experiments (e.g., potentiometer for resistance, spherometer for curvature).
- Practice tables, calculations, graphs, percentage error.
- Understand principles, effects, observations.
- For annual exams 2026 onwards.
