Ohm's Law - Quiz Quiz

Question 1

What effect will the extension cord have on the circuit? Cici uses a long extension cord to plug a lamp into a wall outlet in the next room.

Revolt · Accepted Answer

B: It will increase the resistance in the circuit.

Question 2

What is the unit for resistance?

Revolt · Accepted Answer

B: ohm

Question 3

Which is most likely the analogy that Jason used? Jason sees a news report about a traffic jam caused by a truckload of tires that spilled across the road. The next day in class, he uses the traffic jam as an analogy to explain electric circuits to his friend.

Revolt · Accepted Answer

C: The cars represent moving charges, and the spilled tires represent an increased resistance that causes the current to decrease.

Question 4

Which equation relates charge, time, and current?

Revolt · Accepted Answer

C: I=Δ⁢qt

Question 5

Which changes would cause an increase in the resistance of a wire? Choose three correct answers.

Revolt · Accepted Answer

B: using a longer wire; C: increasing its temperature; F: using a thinner wire

Revolt · Accepted Answer

A: 900 cap c

Question 7

How long does current 2 have to run to deliver the same amount of charge as current 1 ? Current 1 of 8 point 4 cap A runs for 240 seconds and then stops. Current 2 is 10 point 5 cap A

Revolt · Accepted Answer

A: 192 s

Question 8

Which statement correctly describes the formation of an electric current?

Revolt · Accepted Answer

A: A voltage causes electric charges to move from higher to lower potential.

Question 9

What is the unit for measuring electric current?

Revolt · Accepted Answer

B: ampere

Question 10

What is the current in the wire? A wire delivers 12 point 0 cap c of charge in 4 point 0 s
