To determine the circuit's current, use the Ohm's law equation: V = I∙R V = Voltage I = Current R= Resistance Step 1: Determine the total resistance in a series The total resistance in a series is the sum of all resistances. R_total= R₁ + R₂+ R₃ R_total= 4 Ω + 8Ω + 12Ω R_total= 24 Ω Step 2: Use the Ohm's law equation V = I∙R to determine the current in the circuit by converting the equation to solve for the current: I = V/R Insert the values into the equation I = 120/24 I= 5 A
