310102f Series - Parallel Resistive Circuits 2017 (TF)

Series-parallel circuit

A circuit that has multiple paths for current to flow and different values of branch voltages.

Voltage source

A component in a circuit that provides electrical energy, typically a battery.

Conductive path

The pathway through which electric current flows in a circuit.

Resistance

The opposition to the flow of electric current, measured in ohms.

Kirchhoff’s Current Law

The principle stating that the total current entering a junction must equal the total current leaving the junction.

Kirchhoff’s Voltage Law

The principle stating that the sum of the electrical potential differences (voltage) around any closed network is zero.

Total resistance (RT)

The overall resistance in a circuit, calculated based on both series and parallel resistances.

Series Circuit Resistance Formula

RT = R1 + R2 + R3 + … (sum of resistances in series).

Parallel Circuit Resistance Formula

1/RT = 1/R1 + 1/R2 + 1/R3 + … (calculation for equivalent resistances in parallel).

Equivalent resistance

The combined resistance of a group of resistors in a circuit that simplifies the analysis.

Ohm's Law

The relationship between voltage (V), current (I), and resistance (R) expressed as V = I * R.

Branch voltage

The voltage across a component or section in a parallel circuit.

Current (I)

The flow of electric charge in a circuit, measured in amperes (A).
