Question

all formula of chapter electricity class 10​

Answer 1

Answer:

Quantity Formulas Unit

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

Ohm (Ω)

Resistance R R = V / I ohm (Ω)

Power P P = VI Watts (W)

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

Answer 2

$answer$

Quantity Formulas Unit

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)
