Question

Please tell me ALL formulas of chapter Electricity including Current ,Power,Heat,Resistance please give relevant answers.

Answer 1

Ohm's law
Ohm said that the current passing through a conductor is directly proportional to its ends giving heat and other physical activities are kept constant
Mathematically. V~RI
THEN. V=RI

Answer 2

f = kq1q2/ r2
I =q/t
v= w/q
I = (1/r)v
R = pl/q here
h= i2rt
h= vit
p = w/t = vi = i2r = v2/r
electric power efficient n= output power / input power
