For the following pairs of voltages and currents, determine whether the element invoved is a capacitor, an inductor, or a resistor, and determine the value ofC, L, or R and sketeh the curves for( v) and (i) if sufficient data are provided: case A B C D Voltage(v) 80 cos(1571+ 40°) 100 cos(3771 -10°) 500 sin(157t + 30°) 100 sin(3771+ 20°) Current(i) 20 cos(1571-40) 20 sin(3771+ 80°) 1 sin(1571+ 120°) 5 cos(3771+ 20°) For the following pairs of voltages and currents, determine whether the element invoved is a capacitor, an inductor, or a resistor, and determine the value ofC, L, or R and sketeh the curves for( v) and (i) if sufficient data are provided: case A B C D Voltage(v) 80 cos(1571+ 40°) 100 cos(3771 -10°) 500 sin(157t + 30°) 100 sin(3771+ 20°) Current(i) 20 cos(1571-40) 20 sin(3771+ 80°) 1 sin(1571+ 120°) 5 cos(3771+ 20°)
