5. (TCO 1) A two-resistor voltage divider consists of a 10 k? and a 15 k? ohm resistor, with the 10 k? resistor connected to the voltage source and the 15 k? resistor connected to ground. If the output voltage is 2.5 V across the 10 k? resistor, what is the value of the voltage source? (Points : 7) A two-resistor voltage divider consists of a 10 k? and a 15 k? ohm resistor, with the 10 k? resistor connected to the voltage source and the 15 k? resistor connected to ground. If the output voltage is 2.5 V across the 10 k? resistor, what is the value of the voltage source? A 68 ? resistor, a 270 ? resistor, and a 330 ? resistor are in parallel. What is the approximate resistance of the circuit? Determine the phase angle between I = 30cos(?t + 20 degree) and I = 25sin(?t + 70 degree ). Transform into rectangular form. A perfect capacitor with C = 0.3 µF is connected in series to a current source with and peak value of 10 V. What is the reactance of the capacitor? The complex conjugate of 50 ? + j100 ? is
