, Linear Circuit
The homogeneity property:
The additivity property:
, Linear Circuit
• We consider only linear circuits.
• Note that since P=i2R=v2/R (Making it a
quadratic function rather than a linear one),
the relation ship between power and voltage
(or current) is non linear.
• Therefore the theorems covered in DC Circuit
analysis are not applicable to power
P 1 = i1 R
2
P2 = i22R
P3 = (i1+i2)2R = Ri12+Ri22 + 2Ri1i2≠P1+P2
