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

Awesome lecture,
Challenger questions ans:-
1) both C and d are are correct since in both cases no of electrons is coming in fractional part which is not possible due to quantisation of charge
2) current = 1.6 into 10 raise to the power minus 12
First using Q=ne find charge then put in I=Q/T t= 1 sec given therefore ans will be option A.
Nice class sir ❤
A great concept -
After paying so much fees to school , you'll get a simple physics teacher who is there to only complete the syllabus and give you homeworks,
But youTube will give you no. 1 teachers of all time in FREE ( especially Physicswallah).
