17 A sinusoidal current $i_1(t)$ has a phase angle of $-30^\circ$. Also, $i_1(t)$ attains its positive peak 0.25 ms later than current $i_2(t)$. Both the currents have a frequency of 1000 Hz. Determine the phase angle of $i_2(t)$ 02) John has been given three circuit elements. One of them is a pure resistor, another is a pure capacitor and the last one is a pure inductor. Unfortunately, John has mixed the three and now cannot distinguish between the three elements. He names the elements 1, 2 and 3 measures the voltage & current relations for each of them. His results are: For element 1: $v(t) = 100 \cos(200t + 30^\circ) V$ $i(t) = 2.5 \sin(200t + 30^\circ) A$ For element 2: $v(t) = 100 \sin(200t + 30^\circ) V$ $i(t) = 4 \cos(200t + 30^\circ) A$ For element 3: $v(t) = 100 \cos(100t + 30^\circ) V$ $i(t) = 5 \cos(100t + 30^\circ) A$ Help John in determining the type and value (in ohms, henrys, or farads) of the three elements.
