Answer 2

a)

V27+3V48-3V75 = 0

L =V9*3 +3V16*3 -3V25*3 =3V3+12V3-15V3 = 0

P = 0

L = P

=====

b)

V48+V12 =V50

L =V16*3 +V483 =4V3+2V3 =6V3

P =V50 =V25*2 =5V2

L =I= P

=======

c)

(7V12-V48)*V75 =150

L =(7*V4*3 -V16*3) *V25*3 =(14V3-4V3)* 5V3 =70*3 -20*3 =210-60 = 150

P =150

L = P

=====

d)

(V24-V150+V54):V12 = 0

L =(V4*6 -V25*6 +V9*6):V12 =(5V6-5V6):V12 = 0:V12 = 0

P = 0

L = P
