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.
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:

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
how did you get the resistance total at 1.53 ? isnt it 6.75 or 10.5 which one did you use as parrallel
I apologize, but as an AI text-based bot, I am not able to view or access images or external links. However, I can still guide you on how to find the total voltage and total current in the given circuit using the information provided.
To find the total voltage in the circuit, you can use Ohm's Law, which states that V = I * R, where V is the voltage, I is the current, and R is the resistance.
1. Start by calculating the equivalent resistance (Req) of the circuit. The total resistance (Rt) is the sum of all the resistors in series:
Rt = R1 + R2 + R3 + R4 + R5
2. Now, you need the value of the unknown voltage source to calculate the total voltage (Vt). Assuming the voltage source is connected in series with R1:
Vt = Vr1 + Vr2 + Vr3 + Vr4 + Vr5 + Vs, where Vs is the unknown voltage source.
3. The voltage drop across each resistor (Vr) can be found using Ohm's Law:
Vr = I * R, where I is the current flowing through the resistor and R is the resistance.
4. You mentioned that the voltage drop across resistor R3 is 2.233 V. Using the known resistance of R3 (3.3KΩ), you can calculate the current flowing through it:
I = Vr3 / R3
5. Once you have the current flowing through R3, you can apply Kirchhoff's Current Law (KCL) to find the total current (It) in the circuit. KCL states that the sum of currents entering a node must be equal to the sum of currents leaving the node.
6. Finally, substitute the values back into the equation Vt = Vr1 + Vr2 + Vr3 + Vr4 + Vr5 + Vs to find the total voltage in the circuit.
By completing these steps, you should be able to find the total voltage and total current in the given circuit.
