Option (B)
    90V
Option (C)
    105V
Option (D)
    30V
Correct Option:
C
Question Solution:

Eg = 0.4 x 300 = 120V]

Vboost = Eg - Ia(Rs + Ra) = 120 - 300(0.02 + 0.03) = 105V]

Question:-
Option (A)
    -2 V
Option (B)
    -1
Option (C)
    -0.5 V
Option (D)
    0.5 V
Correct Option:
C
Question Solution:

V+ = 0.5 V,  V- = 0.5 V

=

= 0.5 - V0.

V0 = 0.5 - 1 = -0.5 V
