Current and Circuits Quiz UNIT 10 AP PHYSICS

Which of the following safety devices measure or react to specific levels of current?

• Fuse

• Circuit Breaker

• Ground Fault Circuit Interrupter (GFCI in your kitchen)

• All The Above

In an electrical circuit, a voltage difference:

• Supplies energy to make charges flow

• Causes a short circuit

• Is the term used for rate of charge flow

• Wastes energy

How would you draw two resistors in parallel?

• one resistor side by side on a separate branch

• one resistor on top of each other on a separate branch

• both resistors in a row

• side by side or one on top of the other (A and B)

How would you draw a series circuit?

• side by side

• one on top of the other

• both in a row

• everyone knows that there is no such thing as series

Three 6 ohm resistors are in series. What is the total resistance?

• 1/6 ohm

• 6 ohm

• 12 ohm

• 18 ohm

What is the voltage drop across each branch of a parallel circuit?

• 2 V

• 3 V

• 6 V

• depends on whatever the battery is

• $0.006

• $0.06

• $0.60

• $6.0

Which of the following statements best describes the difference between series and parallel?

• Series are battery, parallel are generator

• series have a single path, parallel have two or more paths

• series are used in computers, parallel are only in homes

• series have one switch, parallel have two or more switches

The current in a DC series circuit:

• decreases to zero

• is the same at all points

• is greatest through the highest resistor

• is greatest in the lowest resistor
