Electric Circuits Physics

How can you increase the resistance of a wire? 

• Increasing the temperature of the wire
• Lower the resistivity of the material
• Decrease the length of the wire
• Increase the cross sectional area

How can you decrease the amount of resistance in a wire? 

• Increase the cross sectional area 
• Decrease the length
• Increase the temperature
• Decrease the amount of wires

In a series circuit the current

• Is the sum of all currents going through a resistor
• Increases the more amount of resistors added
• The same throughout the circuit
• Goes back and forth

What kind of circuit is this?

• series
• parallel

What type of circuit is show in the image?

• Series Circuit
• Parallel Circuit

this circuit is .....?

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

When there is only one path for electrons to move through it is called a _____. When one light goes out, they all go out. 

• closed circuit
• parallel circuit
• series circuit
• open circuit

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

• true
• false

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 has more than one path to flow through

What is a Parallel circuit? 

• Has only one path 
• Has more than one path 
• Allows energy to travel through easily 
• Has only one light bulb
