1. Given the following apparent power, what is the reactive power, in VAR? S = 4.2 VA θ = π/7 radians (the answer is 1.82, but show how do you get to this answer) 2. For the following impedance network, determine the magnitude of the equivalent impedance, in Ω. Z1 = 8.5j Ω Z2 = 1.5 Ω Z3 = -7.6j Ω (the picture attached is for this question. the answer is 8.34, but show how do you get to this) 3. When a particular transformer has 80 V applied to its primary coil, 30 V is measured across its secondary coil. What is the turns ratio for the transformer? (the answer is 2.67, show how to get this answer)
