R = V/i = 10/0.5 = 20Ω

V(t) = 10cos50πt = 10cos9000t where 9000t is in degrees because 50π rads/sec * 180°/π radians =9000

i(t) = 0.5cos50πt = 0.5cos9000t where 9000t is in degrees

At 15ms V = -7.07 and i = -0.3536A and they are exactly in phase with each other. 9000*15e-3 = 135°

Physics 2 - Chapter 15: Alternating-Current Circuits | Quizlet

Physics 2 – Chapter 15: Alternating-Current Circuits | Quizlet – 1. Draw the phasors for voltage across each device: resistor, capacitor, and inductor, including the phase angle in the circuit. 2. If there is both a capacitor and an inductor, find the net voltage from these two phasors, since they are antiparallel.You use Kirchhoff's current law and sum the two phasor currents together to get the total current. Say we take the 15 A current as the reference and assume the 10 A current lags by 30ºAnd at the end, voltage and current relationship between the basic circuit elements like resistor, inductor, and capacitor has been explained using phasor diagram.
