i Done my best.i think we
can't simplify more than this.thank you.
300) V and v2 (t) 20 cos(wt 45°) V, find v(t) v1 (t)2(t) If v1(t) =...
Using phasors, find v(t) = v1(t) + v2(t), when v1(t)= 10 cos(50t -π/3) and v1(t)= 88 sin (50t + 300).
2. complex numbers a voltage v(t) is given: v(t)=v1(t)+v2(t)=1 V sin( omega t -45) – 2 V cos(omega t-60) a)convert the voltages to phasors and sketch a phasor diagram of V1,V2 and V b)reduce the expression of v(t) to the form v(t)=Vm cos(omega*t + fi(its angle)) do u see normaly 3 exercise _? Problem 4. laplace transform of discontinuous function for the function illustrated a) sketch f'(t) b)find la place transform of f'(t)
QUESTION 3 5pts If vi(t) = -10 sin(wt - 30°) V and vz(t) = 20 cos(wt +45°) V. find v(t) = V(t) + vz(t)
tanks fa any help
