Substitution:
Solve:
Given:
Top resistor, R1 = 5.00 Ω
Left resistor, R2 = 2.00 Ω
Right resistor, R3 = 3.00 Ω
Bottom voltage source, V = 12.0 V
Unknown:
Total current in the circuit, I_total
Equation:
V = I * R_total
Substitution:
The total resistance in the circuit can be calculated by adding the resistances in series:
R_total = R1 + (R2 + R3) = 5 + (2 + 3) = 10 Ω
V = I_total * R_total
12 = I_total * 10
I_total= 1.2 A
Therefore, the total current in the circuit is 1.2 A.
