Electricity - 01 | Electric Charges and Current | Chapter 12 | NCERT | Class 10 | Udaan

[@rohitkumar2711]

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) 1Ampere = 1000mA 1 Killowaat = 1000W 1 Horse Power = 746W

Solutions of challenger problems: Sol1) (c)- 3.2 × 10^-21 is not possible because when divided by 1.6×10^-19 , it does not give a whole no. That means it's not divisible by 1.6×10^-19 and hence is not a multiple of it. Sol 2) (a)- 1.6×10^-12 As we know, I= Q/t Also, Q= ne => I= ne/t I= 10^7 × 1.6×10^-19 / 1 I= 1.6×10^-12 A like if you find this helpful

Lovely class sir.. Fall in love with physics Hw question answer. 1. Both c and d bcoz the smallest charge that can exist is 1.9★10^-19C 2. Option A Bless me sir....

[@HC-rx7pn]

Aapka answer sahi h magar logic thoda wrong... kyuki yaha number of electrons wala formula lagega.... And if smallest charge is 1.6 * 10^-19 then 3.2 * 10^-19 must not be possible though it is possible for 2 electrons; Just FYI brother😇

Sir Thanks a lot for giving clarity of concept Ans 1)C and D Ans 2)1.6×10^-12 A

[@Avanish0011]

Can you explain question - 1 ?

[@letstry6]

@@Avanish0011 look avanish sir has given the hint that is to use formula (Q = ne) So, Option no. A) Given, Q= 1.6 × 10^-18, e = 1.6×10^-19 , n = ? n = 1.6 × 10^-18/1.6 × 10^-19 n= 16 × 10^-18 × 10/ 16× 10^-19 ×10. 16 se 16 cancel. = 10^-19 × 10^20 = 10 (-19 + 20) n = 10 It means 10e= 1.6 × 10^-18 Or ye bt sir ne bola na ki decimal ya fraction mei agar n ka answer hoga to vo possible nhi hoga Or option A k trh hi B ka answer h but C or D ka answer fraction or decimal k form mei aa rha h or charge ki aisi value possible nhi h . I hope this might be helpful.

Op explanation Rakshak Sir 🔥🔥🔥

[@riyansaikia8216]

Thank you sir for the wonderful lecture.. The H/W question answer would be from my aspects... 1 a) 1.6 × 10 -¹⁸ c because it's less than a charge of electron , a Charge less than the charge on an electron ( 1.6 × 10-19 C) is not possible. And for 2 nd questions It's should be a I think

[@rishima730]

Your 1 ans is wrong

[@IcY200]

1.) 10^-18 is greater than the charge of 1 electron (negative number hai) mujhe D lag raha hai kyunki one electron is 10^-19 x 1.6 but for 10^-22 we need to divide by 100 but thats not possible since we will get 1/100th of an electron

[@SaharshKing]

q=ne Q=10 * 1.6 * 10^-19 Q=1.6 * 10^-18
