Given the circuit below with unknown voltage source and a voltage drop of 2.233 v Volts on resistor R3, with (R1 = 2KΩ, R2 = 1KΩ, R3 = 3.3KΩ, R4 = 4.7KΩ, R5 = 4.7KΩ). Calculate and complete the table below.

Question

I need help finding the total voltage, which would help me find the total current. I was able to find the total resistance. Circuit is below:

Answer 1

replace R4 and R5 with
R4 R5/(R4+R5) = 4.7 *4.7 / 9.4 = 2.35 *10^3 = Rend
R3+Rend+R2 = 3.3 + 2.35 + 1 = 6.65 *10^3 ohms
current through those = (2.233/3.3)*10^-3 amps
= 0.677 *10^-3 amps
so
V = i R = 0.677*10^-3 * 6.65*10^3 = 4.5 volts

Answer 2

how did you get the resistance total at 1.53 ? isnt it 6.75 or 10.5 which one did you use as parrallel
