All Formulas Of Electricity Chapter :-

1) I=Q/t
2) Q=ne
3) V=W/Q
4) V=IR
5) R=Rho×L/A
6) H=V×Q
i) H=VIt
ii) H=I^2Rt
iii) H=V^2t/R
7) P=W/t =E/t
i) P=VI
ii) P=I^2R
iii) P=V^2/R
8) E=P×t
9) Resistance in Series-Rs=R1+R2+R3
10) Resistance in Parallel-1/Rp=1/R1+1/R2+1/R3 (i.e. Reciprocal of R1+R2+R3)

S.I. Unit
Current(I)-Ampere
Charge(Q)-Coulomb
Time(t)-Second
Potential Difference or Voltage(V)-Volt
Resistance(R)-Ohm
Resistivity(Rho)-Ohm meter
Power(P)-Watt
Heat=Energy=Work-Joule

Things to remember for numericals-
1 Kw-1000W
1 Horse Power-746W

it is one shot revision for others but for me it`s full detailed explanation of chapter and it`s crystal clear now

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! ❤

We gain more knowledge from YouTube than online classes 😂😂

Electrical resistivity of the given metallic wire is depend upon - Nature of the material. 👍👍

[gameon]

I can't express how much this channel has helped in my study life. Thanks to this channel and deep thanks to all the teachers. School teachers are also not to be blamed, as they have to cope with time and syllabus, and hence run with the syllabus. But then, Magnet Brains comes to our rescue. Keep growing and may the blessings of God always be with you.

[jeevikashukla]

for 10th level physics NCERT is always turned out to be best... this one shot lecture have been so informative and all the concepts are now crystal clear. thanks allot vibhuti ma'am for coming up with a fresh lecture of electricity, and I really hope that now I will be able to apply all these concepts while solving numericals 🙂🙂🙂

[Neha-kciq]

Resistivity depends upon nature of material. 3.23.35

[mohammadfaizannavi]

And magnet brains is best platform for students to study thanks a lot for all magnet brains team and teachers for give me and other students this opportunity 👏🏻😊

This is very helpful video for us 💖💖, and your teaching style is very well 💞💞, I have no words to express your hard work for us but by the way I love your video very much and you also mam❣❣, thnx a lot❤ mam💕💕

[nujbafatima]

Seeing this awesme video just before 2 days of board Thank you Alot magnet brains as well as Thank you ma'am for such a hard working and useful video😍🙌

[ishitamaheshwari]

This one was the fabulous ...helped me a
lot...thank you magnet brains

[situ-xy]

Thank a lot for simple way of explaining this difficult chapter 💯

TRUE LINE:-- मंजिल उन्ही को मिलती है, जिनके सपनो में जान होती है!! पंख से कुछ नहीं, हौसलों से उड़ान होती है!💓

[sangeetarajpurohit]

Just an amazing channel generally I used to call them as magician😍😍

[sou]

You are the best teacher, love you mam, ap har concept crystal clear bana deti hein, apka laakh laakh shukriyya.

[UrmilaDevi-hbhm]

Mam 1 doubt
Mam hum x-axis par independent value lete h but current toh potential difference par dependent h toh x-axis par toh potential difference ko lena chahiye tha na??

[HARPREETKAUR-yemi]

Electrical resistivity of given wire depend on nature of the material

[nogarpisa]

I really love the explanation of area of cross-section

[razisiddiqui]

@magnet brain, Thank you so much for this video, Magnet brain is one of the best platform where we can get easily everything. Once again thank you 😃
