We can use Ohm's law to find the voltage drop across R₁. V = IR V = (100 Ω) (0.71 mA) V = 0.071 V Now, using Kirchoff's Voltage Law (KVL) we can find the voltage drop across resistor R1. V1 = Vs - V V1 = (5 V) - (0.071 V) V1 = 4.929 V Finally, we can use Ohm's law again to find the current through R1. I = V/R I = (4.929 V) / (1000 Ω) I = 0.00493 A Therefore, the current through R₁ is the same as the current through R1, which is approximately 0.071 A.
