Series circuit

A circuit that has only one path for current flow.

Parallel circuits

Circuits containing two or more parallel paths through which current can flow.

Series-parallel circuits

Circuits that contain both series and parallel current paths.

Which of the following is true regarding a series-parallel circuit?

If a circuit is reduced to an equivalent series circuit, the total resistance is found by adding the loads.

Which of the following is true regarding a parallel circuit?

It has more than one path for current flow.

Who stated that the curront entering, a point must equal the total current leaving that point?

Kirchhoff

Which of the following is true regarding a series circuit?

The current flow is the same through all resistors

Kirchhoff's Voltage Law

The statement that the sum of all the voltage drops in a circuit is equal to the source voltage of the circuit.

Kirchhoff's Current Law

The statement that the total amount of current flowing through a parallel circuit is equal to the sum of the amounts of current flowing through each current path.
