• Combination

True or False: A parallel circuit has multiple paths that the current can take.

• True

• False

What is equal everywhere in a series circuit?

• Resistance

• Voltage

• Current

• Capacitance

What is equal everywhere in a parallel circuit?

• Resistance

• Capacitance

• Current

• Voltage

A parallel circuit has four light bulbs.  Light A receives the full current.  After that, the current splits into two paths: one path contains light bulbs B & C, while the other just contains light bulb D.  Which light bulb is the most dim?

• A

• B/C

• D

A parallel circuit has four light bulbs.  Light D receives the full current.  After that, the current splits into two paths: one path contains light bulbs B & C, while the other just contains light bulb A.  Which light bulb is the brightest?

• A

• B/C

• D

The more batteries you have the _____ the bulb will be.

• brighter

• dimmer

True or False: Two batteries connected in parallel will create a brighter bulb than two batteries connected in series.

• True

• False

A series circuit & a parallel circuit both have 4 resistors.  If you turn off a switch in both circuits, in which circuit would current definitely stop in all resistors?

• Series

• Parallel

• Current would stop in both

• Current would continue in both

Due to internal resistance, a 50 V battery will actually have a _____ voltage output.

• Higher

• Lower
