All Formulas of Electricity:
1) I = Q/t
2) Q = ne
3) V = W/Q
4) V = IR
5) R = Rho x L/A
6)Resistance in Series: Rs = R1 + R2 + R3
7)Resistance in Parallel: 1/Rp = 1/R1 + 1/R2 + 1/R3 (» Reciprocal of R1+R2+R3)
8)H = V × Q
i) H = VIt
ii) H = I²Rt
iii) H = V²t/R
9) P = W/t
i) P = VI
ii) P = I²R
iii) P = V²/R
10) E = P × t
S.I. Units:
Current ( I ) - Ampere
Charge ( Q ) - Coulomb
Time ( t ) - Second
Potential Difference or Voltage ( V ) - Volt
Resistance ( R ) - Ohm Ω
Resistivity ( Rho ) - Ohm meter
Power ( P ) - Watt
Heat = Energy = Work = Joule
Measuring Devices:
Ammeter / Milli Ammeter - for measuring current (always connected in series)
Galvanometer - for measuring small/sensitive currents (we can also get the direction of the current)
Voltmeter - for measuring volts (always connected in parallel)
Ohm Meter - Measures the resistivity
Things to remember:
electron charge = (1.6 x 10⁻¹⁹ C)
1kWh= 3.6 × 10⁶J
1Ampere = 1000mA
1 Kilowaat = 1000W
1 Horse Power = 746W
i hope this list will help you! ❤

Alakh Sir - (Phy, chem) Samriddhi mam - Bio Ritik Sir - Maths DSR - sst Dear Sir - English 🎉🎉🎉🎉 Apun to famous ho rela h 🔥🎉
@devilshorts1156
This man literally completed class 10 physics and chemistry in just 2 weeks hats off to this man. I wish he came in the month of December tab inse hi padhkar syallabus complete kardeta . No doubt rakshak sir and sanya mam bohut accha physics aur chemistry padhaya hai but alakh sir is an emotion for thousands of students

Alakh sir's GUNSHOT is Beast 🥶 🤯
@Sneeha_Paatil
Alakh Sir ki mehnat 🔥🔥🔥+ Hamari mehnat 🔥🔥 = 95%🗿🗿🗿🔥🔥🔥🔥🔥
@kunalijoshimemes31
Don't worry 10THians we have the ability to reach 95% this year ! God bless us ✅🕉️♥️🙏
@NiharikaMourya-f5v
Thanks a lot sir😭🥹 I'm a student of 2025-26 batch and tbh bahut sare teachers ka lecture dekha magar kisi ka samajh nhi aaya but somehow i found your lecture and understood the chapter very well!😭❤️sir aap insaan nhi bhagwaan ho bhagwaan!😭❤️💕idk how to describe my happiness in words but thanks a lot sir!❤ Edit:- tysmm for the likes guys😭❤️

Question no 1 : Answer 1/f = 1/v + 1/u 1/15 = 1/v + 1/-10 1/v = 1/15 - 1/10 1/v = 2+3/30 1/v = 5/30 1/v = 1/6 v = 6 cm Therefore the position of the image is 6 cm.
@NayanDevArse
Leaving at 1:35:38 like to remind me! Completed thankyou to all 💗
@FoxenEditz-here
1:21:36 Object distance (u) = -18 cm Focal length (f) = -12 cm by mirror formula 1/f = 1/v + 1/u 1/f - 1/u = 1/v 1/-12 - 1/-18 = 1/v 1/-12 + 1/18 = 1/v take LCM -3/36 + 2/36 = 1/v -1/36 = 1/v v = (-36)
