Question

formulas of chapter electricity class 10th? ​

Answer 1

p= vi

h=i^2rt

v=ir

q=it

r=resistiv.xlength/area


where p is power
,r is resistance,
v is voltage,
i is current,
q is charge

Answer 2

1.Current I:

I = Q / t

Q = Charge

t = time taken

 2.Voltage V:

V = E / Q

or

V = W / Q

E = Energy, W = Work done

 3.Resistance R:

 R = ρl / A

ρ = Resistivity,

l = length,

A = Area

4.Resistance R:

R = V / I

5.Power P:

P = VI 

Hope this will help you ^_^

6. Conductivity σ:

 sigma = 1 / ρ
