Concepts that repeat
In our data no single concept dominates Experimental Skills. Its questions are spread across the syllabus, so work through every sub-topic rather than a short list.
What the syllabus covers
The 18 listed experiments: vernier calipers, screw gauge, simple pendulum, Young's modulus, surface tension, viscosity, speed of sound, specific heat, metre bridge, Ohm's law, galvanometer, focal lengths, prism, diode characteristics.
A checklist to tick off:
- The 18 listed experiments: vernier calipers
- Screw gauge
- Simple pendulum
- Young's modulus
- Surface tension
- Viscosity
- Speed of sound
- Specific heat
- Metre bridge
- Ohm's law
- Galvanometer
- Focal lengths
- Prism
- Diode characteristics
What to focus on
Least count and zero error for vernier calipers and screw gauge, the principle behind each listed experiment, and which reading or graph gives the required quantity.
A study plan for this chapter
Treat it as a dependable source of marks and keep it in your regular revision cycle. If you divide your Physics time in proportion to recent weightage, this chapter earns about 2% of it.
- Day 1–2: a fast pass over theory and the standard results.
- Day 3: chapter-wise PYQs, then log the mistakes.
- Ongoing: a quick look before each mock test.
