Question

Learning Goal: To practice Problem-Solving Strategy 32.1 for resistor circuit problems. Find the currents through each resistor in the circuit shown on the diagram . Use the following values: epsilon = 12.0 V, R1 = 15.0 Ohm, R2 = 45.0 Ohm, R3 = 25.0 Ohm, and R4 = 20.0 Ohm. Only image found Find the following currents the current I1 through the resistor of resistance R1 = 15.0 Ohm the current I2 through the resistor of resistance R2 = 45.0 Ohm the current I3 through the resistor of resistance R3 = 25.0 Ohm the current I4 through the resistor of resistance R4 = 20.0 Ohm Express your answers in amperes separated by commas. I1, I2, I3, I4 = A

Explanation / Answer

Req = 56.25 ohm

I = V/Req = 12/56.25 = 0.213 A

----------------------------------

I2 = I = 0.213 A

------------------------------------

V1 = 12 - 0.213*45 = 2.415 V

I1 = 2.415 / 15 >>>>> I1 = 0.161 A

-----------------------------------

I3 = I4 = V1/(R3 + R4) = 2.415 /(45) = 0.054 A

I3 = 0.054 A

I4 = 0.054 A

-----------------------------------------------------------

-----------------------------------------------------------

I1 = 0.161 A

I2 = 0.213 A

I3 = 0.054 A

I4 = 0.054 A
