Answer 2

Given Information:

- R1 = 6 Ω - R2 = 12 Ω - R3 = 8 Ω - R4 = 8 Ω - R = 3 Ω - I2 = 3 A

Calculating Currents:

To find the currents (I1, I3, I4, I5), we can use Kirchhoff's current law, which states that the sum of currents entering a junction is equal to the sum of currents leaving the junction.

1. Applying Kirchhoff's current law at junction 1: - I1 = I3 + I4 2. Applying Kirchhoff's current law at junction 2: - I2 = I5 + I3 3. Solving the system of equations formed by the above two equations: - Substitute the value of I2 from the given information: I2 = 3 A - Substitute the value of I2 in equation 2: 3 A = I5 + I3 - Substitute the value of I3 from equation 1: 3 A = I5 + (I1 - I4) - Simplify: 3 A = I1 + I5 - I4 [[4]](https://edu.tusur.ru/publications/5376/download)

4. Applying Kirchhoff's current law at junction 3: - I4 = I5 5. Solving the system of equations formed by equations 3 and 4: - Substitute the value of I4 from equation 4: I4 = I5 - Substitute the value of I4 in equation 3: 3 A = I1 + I5 - I5 - Simplify: 3 A = I1 Therefore, we have the following currents: - I1 = 3 A - I3 = 0 A - I4 = I5 = 3 A - I2 = 3 A [[4]](https://edu.tusur.ru/publications/5376/download)

Calculating Voltages:

To find the voltages (U1, U2, U3, U4, U5), we can use Ohm's law, which states that the voltage across a resistor is equal to the current flowing through it multiplied by its resistance.

1. Calculating U1: - U1 = I1 * R1 = 3 A * 6 Ω = 18 V

2. Calculating U2: - U2 = I2 * R2 = 3 A * 12 Ω = 36 V

3. Calculating U3: - U3 = I3 * R3 = 0 A * 8 Ω = 0 V

4. Calculating U4: - U4 = I4 * R4 = 3 A * 8 Ω = 24 V

5. Calculating U5: - U5 = I5 * R = 3 A * 3 Ω = 9 V

Therefore, we have the following voltages: - U1 = 18 V - U2 = 36 V - U3 = 0 V - U4 = 24 V - U5 = 9 V

Additional Calculations:

- Total resistance (R): - R = R1 + R2 + R3 + R4 + R = 6 Ω + 12 Ω + 8 Ω + 8 Ω + 3 Ω = 37 Ω

- Total current (I): - I = I1 = 3 A

- Total voltage (U): - U = U1 + U2 + U3 + U4 + U5 = 18 V + 36 V + 0 V + 24 V + 9 V = 87 V

Therefore, we have the following additional values: - R = 37 Ω - I = 3 A - U = 87 V

Summary:

Based on the given information and calculations, we have the following values:

- Currents: - I1 = 3 A - I2 = 3 A - I3 = 0 A - I4 = 3 A - I5 = 3 A

- Voltages: - U1 = 18 V - U2 = 36 V - U3 = 0 V - U4 = 24 V - U5 = 9 V

- Additional values: - R = 37 Ω - I = 3 A - U = 87 V

Please note that the above calculations are based on the given information and assumptions.
