Question

QUESTION 3 Find the sum of two sinusoidal voltages, given as follows: v1 (t)=V1 cos(wt+$\phi_1$) and v2 (t)=V2 cos(wt+$\phi_2$). You are told that V1 = 19, V2 = 14, ? = 1,000, $\phi_1$ = 25° and $\phi_2$ = 72°. Hint: we recommend using the phasor transform to add these signals in the frequency domain. Once you have added the signals, please enter the magnitude below. QUESTION 4 A voltage of v(t) = 4.5 cos (16 t - 41°) V is applied across a capacitor C = 1.8 mF as shown. What is the magnitude of the current phasor through the capacitor? i(t) C v(t) Please enter your answer in Amps (A), to 3 significant figures below.
