Question
In the figure shown current i = 10e-4tA. Value of VL and Va - Vb is : -
Options
A.-80 e-4t, -40 e-4t
B.80 e-4t, 10 e-4t
C.-40 e-4t, -80 e-4t
D.Zero, Zero
Solution
VL = + L
= +2
(10e-4t) = -80e-4t
Now Va - iR -
= Vb
Va - Vb = iR +
= 40 e-4t - 80 e-4t
= - 40 e-4t
= +2(10e-4t) = -80e-4tNow Va - iR -
= VbVa - Vb = iR +
= 40 e-4t - 80 e-4t
= - 40 e-4t
