Understand Ohm's law (I = V/R) and how combining resistors in series versus parallel changes the equivalent resistance and therefore the current drawn from the source.

30.00 ΩTotal Current
0.400 AOhm's law: I = V / RSeries: R_eq = R1 + R2Parallel: R_eq = (R1·R2) / (R1 + R2)In Series mode, set R1 = 10 Ω, R2 = 20 Ω, and voltage = 12 V. Confirm the total current is close to 0.4 A.
