Series Circuit

A light switch

• is a resistor

• opens and closes a circuit

• changes voltage

• generates electricity

What do we call the path on which electricity flows?

• switch

• wave

• current

• circuit

Where is the resistor located on this diagram?

• A

• C

• D

• B

what is this symbol for?

• light bulb
• switch
• battery
• resistor

What is the total circuit resistance of the following five resistors connected in series?

R1 = 27 ohms

R2 = 33 ohms

R3 = 51 ohms

R4 = 1200 ohms

R5 = 240 ohms

Rt = __________ Ohms

• 353.2

• 1551

• 1.9 K

The picture shows an electrical circuit. This circuit is a series circuit because: 

• It has 3 light bulbs.
• The same current flows through all three light bulbs.
• It uses a single battery.
• The electrical current is divided between the three light bulbs.

As resistors are added in series to a circuit, the total resistance will...

• increase
• decrease
• stay the same

As the resistance of a circuit increases, the current will...

• increase
• decrease
• stay the same

When the second bulb is added, they get

• brighter

• dimmer

• broken

• cold

Which component provides the energy for the charges?

• cell

• bulb

• switch

• ammeter
