Student Exploration: Circuits (gizmos) questions with correct answers

Suppose a single light bulb burns out. How do you think this will affect lights that are strung along a single wire? CORRECT ANSWER All of the other lights will go out. This is an example of a series circuit. How will a single burned-out bulb affect the string of lights if each light is attached to its own wire? CORRECT ANSWER There will be no change in the brightness of the other lights. This is an example of a parallel circuit. Click the light switch to turn it to ON. What happens? CORRECT ANSWER The light bulb starts to glow. How does changing the battery's voltage affect the current? CORRECT ANSWER The higher the battery voltage, the greater the flow of current in the circuit. How does changing the battery's voltage affect the brightness of the light? CORRECT ANSWER The higher the battery voltage, the brighter the bulb shines. Remove the wire. What happens? CORRECT ANSWER The current stops and the bulb stops glowing. How do you think increasing the resistance in a circuit will affect the current in the wire? CORRECT ANSWER The flow of the current will decrease due to the resistance. Is the current the same throughout, or does it change? CORRECT ANSWER The same What is the current in the wire now? CORRECT ANSWER 2.7 amp
