The expression for voltage regulation of a short transmission line for leading power factor is given by: ____, where, 'I' is the line current, 'V_r' is the receiving end voltage, 'R' is the line resitance and 'X' is the line reactance.

(IRcosφ_r + IXsinφ_r)/V_r

(IXcosφ_r + IRsinφ_r)/V_r

(IXcosφ_r - IRsinφ_r)/V_r

(IRcosφ_r - IXsinφ_r)/V_r

(IRcosφ_r + IXsinφ_r)/V_r

(IXcosφ_r + IRsinφ_r)/V_r

(IXcosφ_r - IRsinφ_r)/V_r

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) sin[1/√(LC)]t A

i(t) = (E/R) sin√(LC) t A

i(t) = (E/R) cos[1/√(LC)]t A

i(t) = (E/R) cos√(LC) t A

i(t) = (E/R) sin[1/√(LC)]t A

i(t) = (E/R) sin√(LC) t A

i(t) = (E/R) cos[1/√(LC)]t A
