Question

A power system network with n nodes, $Z_{33}$ of its bus impedance matrix is j0.5 per unit. Voltage at node 3 is 1.3$\angle -{10}^o$ per unit. If a capacitor having reactance of -j3.5 per unit now added to the network between node 3 and the reference node, the current drawn by capacitor per unit is

• A. $0.325\angle -{100}^o$
• B. $0.325\angle {80}^o$
• C. $0.433\angle -{100}^o$
• D. $0.433\angle {80}^o$

Answer 1

The correct option is D $0.433\angle {80}^o$

$0.433\angle {80}^o$
