Study Notes
Series Circuit Formulas
- Total voltage (Vt) in a series circuit is calculated by adding individual voltages: Vt = V1 + V2 + V3.
- Total current (It) remains constant throughout a series circuit: It = I1 = I2 = I3.
- Total resistance (Rt) is the sum of individual resistances: Rt = R1 + R2 + R3.
Parallel Circuit Formulas
- Total current (It) in a parallel circuit is the sum of the individual currents: It = I1 + I2 + I3.
- Total voltage (Vt) across all components in a parallel circuit is equal: Vt = V1 = V2 = V3.
- Total resistance (Rt) is calculated using the reciprocal formula: 1/(Rt) = 1/(R1) + 1/(R2) + 1/(R3).
