Hello guys,🫡💯
All Formulas of Electricity:
1) 1 = 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 = Vlt
ii) H = I2Rt
iii) H = V²t/R
9) P = W/t
i) P = VI
ii) P = I2R
iii) P = V2/R
10) E = P x t
S.I. Units:
Current (1) - 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
1 Ampere = 1000mA
1 Kilowaat = 1000W
1 Horse Power = 746W
Thank u guys ❤

For 5th question :
Resistors in series:
1\5+1\5+1\5+1\5+1\5=1
Resistors in parallel:
1\1\5=5
So 5+5+5+5+5 =25
The answer changes
Please reply for it sir
Please reply for it sir and any students
Please reply for it sir and any students
sir what about challange 100 science ?
Same doubt
SIR IF RATAN SIR IS OUR TEACHER.THEN U ARE MY MOST LEGENDARY TEACHER WHO IS THE ONLY GOD OPENED MY EYE IN (PCM)✌✌✌✌✌✌U R MY LOVED MASTER TEACHER I AM WAITING FOR U TO COME TRICHY .
4:44 the quiz starts here
Thanks a lot sir!!
