Fill-in the blanks. Assume E = 100 V. Show your step-by-step solution with simplified schematic diagram in every step. Resistance II. Voltage Current Calculate the following. Fill-in the blanks. (2 points each) 1. Calculate the voltage at RL when the selector switch is at positions V1, V2, and V3. Selector position V1 V2 V3 Voltage at RL 81.0596265 V 52.30769231 V 27.01986755 V 2. With 30 V applied across two equal resistors in series, 10 mA of current flows. Calculate the value of R1 and R2. R1 R2 1.5 kΩ 1.5 kΩ 3. Basing on the figure below, rank the total resistance of the following (in order from highest resistance to lowest resistance). Assume that each bulb has the same rating and type. Example: A__ greater than C__ greater than E__ greater than B__ greater than D__ greater than Your answer: _B_ greater than _E_ greater than _A_ greater than _D_ greater than _C_ 4. Calculate the output voltage, Vo of the power supply shown below. I2 = 2.71/1.5k = 1.8066666 mA E = E3.3k + E2.7k + E1.5k E = (1.806666 mA) (3.3k+2.7k+1.5k) E = 13.55 V Vo 13.55 V
