What is the magnitude of the current through R1? DATA: R1 = R2 = R3= 18.0 Ω. V1 = 6.0 Volts. V2 = 2V1.
V1 = I1R2 + I1R1 (1)
V2 = I3R3 + I2R3 (2)
I3 = I1 + I2 (3)
putting 3 into 2, we get
V2 = I1R3 + I2R3 + I2R2 (4)
solving 1 for I2 and putting into 4 and solving for I1 we get
V1 = -I2R2 + I1R1
I2 = (I1R1 - V1)/R2
I1 = (V1 + V1 + V1 x R3/R2)/(R3 + R1R3/R2 + R1)
I1 = (6 + 12 + 6x18/18)/(18 + 18x18/(18+18) + 18)
I1 = 24/(18 + 9 +18) = 0.533 A
Hence, I1 = 0.533 A
