Question

All formulae for Electricity class 10

Answer 1

Explanation:

I THINK IT WILL HELP YOU DEAR MATE

Answer 2

Explanation:

Current I I = Q / t

Q = Charge

t = time taken

Amperes (A)

Voltage V V = E / Q

or

V = W / Q

E = Energy, W = Work done

Volts (V)

Resistance R R = ρl / A

ρ = Resistivity,

l = length,

A = Area

or,

R = V / I

Ohm (Ω)

Power P P = VI Watts (W)

Conductivity σ sigma = 1 / ρ Siemens per meter (S/m)

Electricity Formulas are applied in calculating the unknown electrical parameters from the known in electric circuits.
