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.

υ = 550 sin (377t + 50°)

i = 11 sin (377t − 40°)

---

b.

υ = 36 sin (754t − 80°)

i = 4 sin (754t − 170°)

---

c.

υ = 10.5 sin (ωt − 13°)

i = 1.5 sin (ωt − 13°)
