1. In a two-element series circuit, the applied voltage and the resulting current are respectively v(t) = 50 + 50 sin(5 × 10³t)V and i(t) = 11.5 sin(5 × 10³t + 63. 5°)A. The nature of the elements would be a) R-L b) L-C c) R-C d) R-L-C 2. Three equal impedances are connected in star across a balanced 3-phase supply, if connected in delta across the same supply, state if a) power consumed will increase three fold b) phase current will be tripled c) line current will become one-third d) phase current will be doubled
