Use phasor methods to find a voltage

Reference no: EM131344460

1. Given a sinusoid v₁(t) whose phasor is V₁ = 4 - j 3 V, use phasor methods to find a voltage v₂ (t) that lags v₁ (t) by 90 and has an amplitude of 10 V.

2. A new parameter Z is defined as V/I. If V = 9.85 + j 1.74 V and i(t) = -4 sin (ωt) A, find Z

3. Complex power S is defined as VI^∗, where I^∗ is the complex conjugate of the current phasor. If V = 1200 + j 1600 V and I = 800 - j 600 mA, find S.
