3 Last-Minute Unique Tips for CLASS 10 Science Boards Exam 2024! 🔥

Thank you sir

i will study 1 hour per like

All Formulas of Electricity
1) I=Q/T

2) Q = ne

3) V = W/Q

4) V=IR

6) Resistance in Series: Rs= R1+ R2+R3

5) R = Rho x L/A

7) Resistance in Parallel: 1/Rp=1/R1+1/R2 +1/R3 ( Reciprocal of R1+R2+R3)

8)H= V x Q

i) H-Vlt

ii H=I^{2}Rt

iii) H=V^{2}T/R

9) P=W/t

i) P-VI

ii) P = I²R

iii)P=V^{2}/R

10) E=P × T

S.I. Units:

Current (1)-Ampere

Charge (Q) Coulomb

Time (1) Second

Potential Difference or Voltage (V)-Volt

Resistance (R)-Ohm

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 (1.6times10^{-19}C)

1kWh =3.6times10^{circ}J

1 Ampere 1000mA

1 Kilowaat t=1000W

1 Horse Power = 746W

i hope this list will help you!
