Physics: Circuits & Ohm's Law

Suppose a single light bulb burns out. How do you think this will affect lights that are strung along a single wire?

• The remaining lights will get brighter

• Only the burned-out bulb will go out.

• 
  All the lights will go out.

  
  

• Nothing will happen.

How will a single burned-out bulb affect the string of lights if each light is attached to its own wire?

• The entire string will go out.

• Only the burned-out bulb will go out.

• All bulbs will become dim.

• The remaining bulbs will flicker.

What will happen if you turn the switch to ON. What happens?

• The light turns on.

• The light turns off.

• Nothing happens.

• The switch breaks.

What happens when you turn on Show current and select Electron flow?

• The direction of electron movement is displayed.

• The circuit diagram changes color.

• The voltage increases.

• The simulation stops.
