On the left a Circuit A, which is a square box. The top, left, and right sides have circles with X's in them. The bottom side has a stack of vertical lines, which are from left to right very short, short, very short, short. On the right a Circuit B, which is a square box. 2 extra lines cross the box near its top, parallel with the top side. The top side and the 2 extra lines have circles with X's in them. The bottom side has a stack of vertical lines, which are from left to right very short, short, very short, short.

Which circuit is a parallel circuit?

Which circuit is a series circuit?

In which circuit do the light bulbs all shine at their maximum brightness?

Circuits can be connected in series or parallel but the maximum voltage is obtained in series connection, thus, light bulbs shine brightest in series connection.

What is parallel and series connection in a circuit?

A parallel circuit connection is one in which the terminals of all the components in th circuit meet at two points.

The components are parallel to each other and current flows in multiple directions.

A series connection in a circuit is one in which the terminals of the component parts in a circuit are joined end to end. Current flows in one direction.

The voltage in a series connection is the sum of all the individual cells, therefore, the light bulb in series connection shines brightest.
