Question

tell me all the formulas of electricity chapter of .. class 10th............??????£%&@@'+*=:!,

Answer 1

Hey frnd....
Ur answer...

》To calculate Potential difference,

V = W / Q
i.e.
work done by quantity of charge moved.

》 To calculate Current,

I = Q / t
i.e. Current by time.

》 From ohms law,,
V= IR
where R is Resistance.

》To calculate Resistance,

R = rho × l / A
where l is length and A is area.

》 To calculate resistivity or rho,

rho = R × A / l

》 To calculate power,

P = W / t
ime. work done by time taken.

• P = VI
• P = I×I×R
• P = V×V/R

》 To calculate heating effect,

H = I×I× R×t

And most importantly,,
1kWh is 3.6 × 10 to the power 6 Joules.
i.e. 3600 × 1000 J
