Experiments in the Laboratory
The study of physics is incomplete without experiments. The NIOS Practical component allows for the verification of theoretical law through hands-on experimentation.
Sample Experiments Include the Following:
- The resistance of a circuit can be calculated by using Ohm's Law
- A potentiometer is used to measure emf
- Finding the focal length for a convex lens
- The characteristic curve for a semiconductor
- A Meter Bridge can be used to measure the resistance in a wire
- Tracing the path rays using prisms and a lens
- Finding wavelength using a diffraction grating
- Researching resonance in the LCR Circuit
Each practical includes a goal, apparatus, procedure, and observation table. The format is exactly the same as NIOS's expectations.
Formula Reference Sheet
Unnati Education PDF contains a section devoted to formula banks, arranged by topic.
Key Formulas Snapshot:
- Electrostatics: \( F = \frac{1}{4\pi \epsilon_0} \frac{q_1 q_2}{r^2} \)
- Current: \( V = IR \), \( P = VI \)
- Magnetism: \( F = qvB \sin\theta \), \( B = \frac{\mu_0 I}{2\pi r} \)
