All formulas used in electricity chapter class 10 science

Answer»

QuantityFormulasUnit Current I I = Q / t

Q = Charge

t = time taken

 Amperes (A) VOLTAGE VV = 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)
