NUC 255 M2A1 Problem Set #1 1. Find the values of V and i in below circuit (10 points) 3. Use the voltage-division principle to calculate V1, V2, and v3 in circuit below. (10 points) R] = 5 Q zsve R2=7Q R3=130 4. A series-connected circuit has a 240V voltage source, a 10-9 resistance, a 5-9 resistance, and an unknown resistance Rx. The voltage across the 59 resistance is 30 V. Determine the value of the unknown resistance. (20 points) 5. We have a 15-V source and a load that absorbs power and requires a current varying between 0 and 100mA. The voltage across the load must remain between 4.7 and 5.0 V for all values of load current. Design a voltage-divider network to supply the load. You may assume that resistors of any value desired are available. Also, give the minimum power rating for each resistor. (20 points) 6. The Wheatstone bridge shown below is balanced with R1 = 1 k9, R3 = 34199, and R2 = 1 k9. Find RX. (20 points)
