Circuits

What kind of circuit is this?

• series
• parallel
• simple

In a parallel circuit if one light bulb goes OUT; then they ALL go out. 

• TRUE
• FALSE

In a Series circuit the more light bulbs you add 

• the brighter the light bulbs get.
• the dimmer the light bulbs get. 
• the brightness of the bulbs remains unchanged.

What is a Parallel circuit? 

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

A material in which electrons are able to move easily

• Circuit
• Insulator 
• Resistance 
• Conductor

A correct statement of Ohm’s Law is:

• I= V R
• V ∝ I
• V = IR
• both b and c

The equivalent resistance in this circuit is 

• 100 ohms
• 450 ohms
• 400 ohms
• 30 ohms

The current going through the 90 ohm resistor is 

• 10 amps
• 0.1 amps
• 0.2 amps

If the voltage across the battery was 10V in this diagram. What would the voltage across each bulb be?

• 10V
• 5V
• 20V
• 0V
