Repeat Problem for the following pairs of voltages and currents with ω = 157 rad/s.
a. ʋ = 2000 sin ωt i = 5 cos ωt
b. ʋ = 80 sin(157t + 150°) i = 2 sin(157t + 60°)
c. ʋ = 35 sin(ωt – 20°) i = 7 cos(ωt – 110°)
Problem
For the following pairs of voltages and currents, indicate whether the element involved is a capacitor, an inductor, or a resistor, and find the value of C, L, or R if sufficient data are given:
a. ʋ = 550 sin(377t + 50°) i = 11 sin(377t – 40°)
b. ʋ = 36 sin(754t – 80°) i = 4 sin(754t – 170°)
c. ʋ = 10.5 sin(ωt – 13°) i = 1.5 sin(ωt – 13°)
