📊 Physics Practical — Marks Distribution
Board practical kaise divide hota hai, ek nazar me.
| Component | Marks |
|---|---|
| Two experiments — ek Section A se, ek Section B se | 7 + 7 |
| Practical record (experiments + activities) | 5 |
| One activity — kisi bhi section se | 3 |
| Investigatory Project | 3 |
| Viva on experiments, activities & project | 5 |
| Total Practical Marks | 30 |
⚠️ Ye CBSE ka standard practical scheme hai. Marks breakup kabhi-kabhi revise hota hai, isliye apne session ka official CBSE curriculum document ek baar zaroor check kar lein.
❓ Class 12 Physics Practical — FAQs
Section A/B, activities, file aur viva se jude common sawaal.
Class 12 Physics practical me Section A aur Section B kya hota hai?
CBSE Class 12 Physics ka practical syllabus do hisson me bata hai. Section A mainly Current Electricity, Moving Charges and Magnetism aur Alternating Current par based hai — ismein 6 Experiments + 6 Activities hain. Section B mainly Ray Optics, Wave Optics aur Semiconductor Electronics par based hai — ismein 9 Experiments + 7 Activities hain. Board practical me dono sections me se ek-ek experiment diya jata hai.
Experiment aur Activity me kya farak hai?
Experiment me observation table banani hoti hai, readings leni hoti hain, calculation aur zyadatar graph plot karna hota hai, aur ek numerical result nikalta hai. Activity chhoti hoti hai — ismein mainly observe karna, identify karna ya circuit assemble karna hota hai, aur result descriptive hota hai. Board me experiment ke marks zyada hote hain (7+7) aur activity ke kam (3).
CBSE Class 12 Physics practical kitne marks ka hota hai?
Physics ka practical component aam taur par 30 marks ka hota hai — do experiments (7+7), practical record (5), ek activity (3), investigatory project (3) aur viva voce (5). Upar di gayi table me poora breakup diya hai. Exact distribution har session ke official CBSE curriculum document me rehta hai, isliye apne year ka latest syllabus check kar lein.
Class 12 Physics practical file kaise banayein?
Har experiment ko is order me likhein — Aim → Apparatus Required → Theory & Formula → Circuit/Ray Diagram → Procedure → Observation Table → Calculations → Graph → Result → Precautions → Sources of Error. Diagram aur graph hamesha blank ya graph page par pencil se banayein, aur observation table ruled page par. Upar kisi bhi card ko kholkar ready-made format copy kar sakte hain.
Metre bridge me balance point beech me kyun rakhte hain?
Balance point wire ke beech (lagbhag 40 cm se 60 cm ke beech) rakhne par percentage error sabse kam hota hai, kyunki tab dono lengths comparable hoti hain aur end corrections ka asar kam ho jata hai. Agar null point kinaare par aa raha ho to resistance box ki value badal dijiye.
Convex lens ka focal length graph se kaise nikalta hai?
u–v graph ek hyperbola deta hai, aur origin se khinchi 45° wali line jahan curve ko kaatti hai wahan u = v = 2f hota hai. 1/u–1/v graph ek straight line deta hai jiske dono intercepts 1/f ke barabar hote hain. Dono me se kisi bhi method se focal length nikal aati hai — Experiment B-3 me poora steps diya hai.
Kya ye saare Physics practicals free me available hain?
Haan. EduGrown par Section A aur Section B ke saare 28 practicals aur activities CBSE pattern ke according English medium me available hain. Kisi bhi card ke "Open Practical / Open Activity" button par click karke poora procedure, observation table, graph aur result dekh sakte hain.
Physics practical viva ki taiyari kaise karein?
Har experiment ka Aim, formula aur symbols ka meaning, apparatus ka principle, graph ka shape aur 2–3 precautions yaad rakhein. Section A me sawaal zyadatar Ohm's law, Wheatstone bridge, galvanometer, shunt aur resistivity se aate hain; Section B me mirror/lens formula, refractive index, prism, diffraction aur diode biasing se. Upar diye progress tracker se check karte rahiye kaunse baaki hain.
