Pada listrik, berlaku energi listrik, W = I² R t atau R = W / (I² t)
Satuan R = satuan W / (satuan I² x satuan t)
Satuan R = joule / (ampere² x sekon) = kg m² s^-2 / (ampere² x sekon)
Satuan R = kg m² s^-3 A^-2
Dimensi R = [M] [L]² [T]^-3 [I]^-2
* Dimensi tegangan listrik
Pada listrik statis, berlaku P = V I atau V = P/I
Satuan V = satuan P / satuan I
Satuan V = watt / ampere = (joule/sekon) / ampere = kg m² s^-2 s^-1 A^-1
Dimensi V = [M] [L]² [T]^-3 [I]-1
*Dimensi kapasitas kalor
Q = C ∆T atau C = Q/∆T
Satuan C = satuan Q / satuan ∆T = joule / kelvin
Satuan C = kg m² s^-2 / K
Dimensi C = [M] [L]² [T]^-2 [θ]^-1
maaf klau slh dan kasi terbaik dan trims
