******

All Formula's of Electricity chapter :-

➡I = Q / T

➡V = W / Q

➡V = R × I

➡P = V × I

➡P = W / T

➡P = I^2 × R

➡P = V^2 / R

➡R = R1 + R2...

➡1 / R = 1 / R1 + 1 / R2...

➡R = resistivity × Length / Area

➡resistivity = resistance × Area / Length

➡H = I ^2 × R × T

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)
