UPDATED Exam Questions and
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
What is the mathematical relationship between voltage (V), resistance (R), and current (I)? -
Correct Answer- V= IxR
