Find the voltage across r1 - find the current - what is the

Question

Question 1:

R₁ = 3 Ohm
R₂ = 8 Ohm
R₃ = 6 Ohm
R4 = 2 Ohm

The measured node voltages (relative to the ground node) are:
V_a = 5.000 V
V_b = 2.857 V
V_c = 0.714 V

• Find the voltage across R1 (you could use KVL):
V_ab =___Volts

• Find the current (use Ohm's law):
I₁ =___A

• What is the power for the voltage source? Remember: P should be negative if power is being delivered from it and positive if power is being absorbed by it.
P=___W

• Compute the currents (use Ohm's law):
I₂ =____A
I₃ =____A

Question 2:

R₁ = 8 Ohm
R₂ = 3 Ohm
R₃ = 10 Ohm

The measured node voltages are:

V_a = 19.000 V
V_b = 23.190 V
V_c = 24.762 V

Hint: Pay attention to the expected units and, for the power questions, pay attention to the sign!

• Find the voltage V_ab, and the current I₁:
V_ab=____volts

I₁=____mA

• What is the power for the voltage source?
P_voltage source =____W

• What is the power for the current source?
P_current source = ____W.
