The relation between electric intensity E, voltage applied V and the distance d between the plates of a parallel plate condenser is

E = V x d

E = V/(d)²

E = V/d

E = Vx(d)²

E = V x d

E = V/(d)²

E = V/d

E = Vx(d)²

In the circuit of figure, the switch is closed to position-1 for a long time. At t = 0 the switch position is changed from postion-1 to postion-2. Find an expression for the current i(t).

i(t) = (E/R) cos√(LC) t A

i(t) = (E/R) cos[1/√(LC)]t A

i(t) = (E/R) sin√(LC) t A

i(t) = (E/R) sin[1/√(LC)]t A

i(t) = (E/R) cos√(LC) t A

i(t) = (E/R) cos[1/√(LC)]t A

i(t) = (E/R) sin√(LC) t A

i(t) = (E/R) sin[1/√(LC)]t A

The line currents in amperes in phases a, b and c respectively are 500 +j150, 100 – j600 and – 300 + j600 referred to the same reference vector with phase sequence of abc. Find the symmetrical component of currents.

Ia₀ = (100+j50) AIa₁ = (546.41+j165.47) AIa₂ = (-146.41-j65.47) A

Ia₀ = (100+j50) AIa₁ = (200+ j107.75) AIa₂ = (200-j107.75) A
