Ohm's Law

Question 1

What is the tendency of a material to oppose the flow of charge?

Revolt · Accepted Answer

resistance

Question 2

A current of 6.0 A runs through a circuit for 2.5 minutes.How much charge was delivered to this circuit?

Revolt · Accepted Answer

900 C

Question 3

What is the continuous flow of electric charge?

Revolt · Accepted Answer

current

Question 4

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.Which is most likely the analogy that Jason used?

Revolt · Accepted Answer

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

Question 5

Which changes would cause an increase in the resistance of a wire? Check all that apply.increasing its temperaturedecreasing its temperatureusing a longer wireusing a shorter wireusing a thicker wireusing a thinner wire

Revolt · Accepted Answer

increasing its temperature; using a longer wire; using a thinner wire

Question 6
