Two ac voltage sources are connected in series with a resistor R = 25 . One source

Question:

Two ac voltage sources are connected in series with a resistor R = 25 Ω. One source is given by V1 = (5.0 V) cos (ωt – a), and the other source is V2 = (5.0 V) cos (ωt + a), with a = π/6.

(a) Find the current in R using a trigonometric identity for the sum of two cosines.

(b) Use phasor diagrams to find the current in R.
