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

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

Does this diagram represent a series or parallel circuit?

• series circuit
• parallel circuit

What is the definition of electrical current?

• The opposition to the flow of electrons

• The rate of flow of charge

• The work done on each coulomb of charge

• Electrons moving around
