HPS Unit 11

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.

What is the total resistance (RT) across this circuit?

• 3 kΩ
• 10 kΩ
• 13 kΩ
• 16 kΩ

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

• increase
• decrease
• stay the same

What is a switch's function in a circuit?

• to make the current hotter or colder
• turn on and off the flow of current
• the pathway that current flows
• to add more power to the circuit

this circuit is .....?

• open
• parallel
• closed
• The cutest little circuit evah!

When all parts of the circuit are connected it is a ______ circuit. 

• open
• closed

When you flip a light switch on and off you are closing and opening a circuit.

• true
• false

An object through which electrons can easily flow is called a(n) ___________.

• Conductor
• Insulator

What is a common energy source for a circuit?
