To find the current through R₃, we must first find the total resistance in the circuit using series and parallel circuit rules. First, resistors R1, R2, and R3 are in parallel with one another. Their combined resistance is: 1/Rtotal = 1/R1 + 1/R2 + 1/R3 1/Rtotal = 1/120 + 1/560 + 1/200 1/Rtotal = 0.0238 Rtotal = 42 Now, we can combine this resistance in series with resistor R₃: Rtotal = 42 + 130 Rtotal = 172 We can now find the current using Ohm's Law: I = V/R I = 7.4/172 I = 0.043 A Therefore, the current through resistor R₃ is 0.043 A.
