1.	R1 = 1Ω, R2 = 3Ω, R3 = 5Ω and R4 = 7Ω connected in series. Total voltage = 20V, Current I, V2 =?(a) I = 1.23, V2 = 3.75(b) I = 1.25, V2 = 3.75(c) I = 1.15, V2= 3.73(d) I = 1.16, V2 = 3.72The question was asked in a job interview.My doubt stems from The Voltage Divider and Current Divider Circuits in portion Simple Resistive Circuits of Electric Circuits
Answer» RIGHT CHOICE is (b) I = 1.25, V2 = 3.75 Explanation: I = 20/ 1 + 3 + 5 + 7 = 1.25A V2 = V. R2 / R1 + R2 + R3 + R4 = 20(3)/16 = 3.75V.
