Unit 6 Test

Which of the following are true about the resistance of a material?

• Longer wires have higher resistance

• Thinner wires have higher resistance

• Shorter wires have higher resistance

• Thicker wires have higher resistance

• Type of wire will change resistance

What is this component?

What is the total resistance of this circuit if the three resistors are each 2 ohms and the battery is 12 volts? (spell out the label completely)

What is the total power of this circuit if the three resistors are each 2 ohms and the battery is 12 volts? (do not forget your label!)

The electrostatic force between two charged particles is 8 Units. If the distance between the two particles is doubled, the charge of one particle is tripled and the charge of the other particle is halved, what will the new force be? (The label is Units)
