Series Circuit Analysis

In a series circuit every component carries the same current. Resistances add directly.

Formulas

R_total = R1 + R2 + R3

I = V / R_total

V_Rn = I x Rn

The sum of all voltage drops equals the supply voltage (Kirchhoff's Voltage Law).

Exemplo Resolvido

12 V supply with 100, 200, 300 ohm resistors in series.

  1. R_total = 100 + 200 + 300 = 600 ohms
  2. I = 12 / 600 = 0.02 A
  3. V_R1 = 0.02 x 100 = 2.0 V
  4. V_R2 = 0.02 x 200 = 4.0 V
  5. V_R3 = 0.02 x 300 = 6.0 V
  6. Check: 2 + 4 + 6 = 12 V
