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) H = V × Q
i) H = VIt
ii) H = I²Rt
iii) H = V²t/R
7) P = W/t
i) P = VI
ii) P = I²R
iii) P = V²/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 (» Reciprocal of R1+R2+R3)

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
1A = 1000mA
1 Kw = 1000W

1 Horse Power = 746W

Sir, Main reason I watch byjus in youtube is to understand the concept in English as most of the other channels use Hindi.. Please Use english Mainly.. thanks!:)

[Education-network...]

You people are working for long hours so that we students can get all concepts clear and at one go...A huge round of applause 👏 🙌 for the entire team...

[abdullkareem]

bruh there are many students who dosnt know hindi...i am a student from tamilnadu...pls tell the concepts in english ....pls

Sir you forgot to tell us the kite story
Question answer wale session mein batana
But a very interesting session🙃🙂😀😃

[pratiksolanki]

Hello sir my name is Devi and I live in New Zealand is there a chance I could enter ANTHE and also can you please make a video of the fundamental properties of chemistry. Also I am very keen on joining BYJU'S but unfortunately I cant access it is there another way I could access it.

[aakshitasingh]

A property associated with object due to which they show electric and magnetic phenomenon is called charge

[dhairyasakhare]

Sir sach bolu toh Jo chapter mein aur kisi se samajh nhi pata woh aapse ache se samajh leta hun
Thank you sir and team

[khyati]

Lots of love from current byjus student!!!🥰♥️♥️

[VijaySharma-dwtu]

1 amphere is defined as : when the one coulamb charge is flow in the wire

[dharan]

Sir please use English I can't understand Hindi

[ghousepasha]

Avoid reading comments so much time waste, flow breakage, not required, concentrate on teaching sir

[sapnakumari]

Why the filament used in bulbs are coiled. ??? 😊

[islamic_]

Where can i get noteses for this chapter .
Sirr plzz replyy
I am already subscriber of byjus
