For the following pairs of vottages and currents, determine whether the element involved is a capacitor, an inductor, or a resistor, and determine the value ofC, L, or R and sketch the curves for( v) and (i) if sufficient data are provided: case A C Voltage(v) 80 cos(157t+ 40°) 100 cos(377f-10°) 500 sin(157t + 30°) 100 sin(3771+ 20°) Current(i) 20 cos(1571- 40P) 20 sin(3771+80°) 1 sin(1571+ 120°) 5 cos(3771+ 20°) For the following pairs of vottages and currents, determine whether the element involved is a capacitor, an inductor, or a resistor, and determine the value ofC, L, or R and sketch the curves for( v) and (i) if sufficient data are provided: case A C Voltage(v) 80 cos(157t+ 40°) 100 cos(377f-10°) 500 sin(157t + 30°) 100 sin(3771+ 20°) Current(i) 20 cos(1571- 40P) 20 sin(3771+80°) 1 sin(1571+ 120°) 5 cos(3771+ 20°)
