Unit 3

Question 1

Flow Rate

Answer 1

of charges that pass a certain point. Per second

Question 2

Series

Answer 2

Bulbs in a single path, one after another

Question 3

Resistance

Answer 3

reduces charge flow

Question 4

Parallel

Answer 4

More than one pathway, bulbs side by side

Question 5

Short Circuit

Answer 5

Charge is taking the path of least resistance, usually by passing bulbs

Question 6

Genecon

Answer 6

Hand held device with a motor to push and pull charge

Question 7

Conductance

Answer 7

Electric current flowing through the circuit

Question 8

Branches

Answer 8

Connections between nodes, thing you need three wires and are like a T

Question 9

Capacitor

Answer 9

A device that stores charge in a circuit. Can charge and discharge

Question 10

Terminal

Answer 10

Positive and negative used to transfer current to power the circuit

Question 11

Identify filaments as parts of circuits that resists charge flow

Answer 11

Round filament- bigger thicker, less resistance
Long- thinner and shorter but has higher resistance

Question 12

Be able to use bulb brightness and compass deflection to show flow rate

Answer 12

The higher the deflection and brightness, the more flow in the circuit

Question 13

Distinguish flow rate from flow speed

Answer 13

Flow speed is how fast the flow moves
Flow rate is how much volume moves

Question 14

Show flow rate and brightness on different diagrams

Answer 14

Color code practice

Question 15

Be able to explain how series and parallel lower or raise resistance

Answer 15

Series adds more resistance because there is only one path compared to parallel who has less resistance because there are multiple paths and charge takes the shortest path

Question 16

Describe vide ce that connecting wires have much less resistance than bulbs

Answer 16

Wires have barely any resistance and don’t stop flow compared to bulbs that have higher resistance and stop flow. Evidence is that when color coding bulbs are able to make the flow switch colors
