PROBLEM 1: A combination of three resistors R1, R2 and R3 in series is connected across a voltage source Vr. The voltage drop across R, and R3 are 10 V and 36 V, respectively. If the current supplied by the source voltage is 1.4 A and the total power supplied by the source is 70 W, Calculate the following: A. The value of Vr and the voltage drop across R2 (Ans. VT = 50 V, V2 = 4 V) B. The equivalent resistance across the voltage source, and the values of R1, R2 and R3 (Ans. Req C. The power dissipated by each resistor (Ans. P1 = 14 W, P2 = 5. 6 W, P3 = 50.4 W) = 35.7143 N, R1 = 7.1429 N, R2 = 2.8571 N, R3 = 25.7143 N)
