Unit 4

Question 1

Compress

Answer 1

Shortening/squeezing the volume PLUS

Question 2

Deplete

Answer 2

To lower charge in a circuit MINUS

Question 3

Give evidence that Mobil charge in a capacitor plate can be compressed

Answer 3

Plunger/syringe experiments

Question 4

Explain how high and low electric pressure in compression/depletion of charge

Answer 4

High electrical pressure compresses into the top plate and depletes and lowers in the bottom plate

Question 5

Cite evidence that a battery creates high and low pressure

Answer 5

Red dot/top of the battery always creates high pressure
Blue/bottom dot always creates low pressure

Question 6

Explain how a battery and wires create a pressure difference that lights a bulb

Answer 6

Battery creates a pressure difference because the top of the battery always generates high pressure and the bottom low pressure and the wires create the difference by carrying out the pressures that the batteries make into bulbs

Question 7

Color coding

Answer 7

Practice

Question 8

Why is pressure uniform in any wire

Answer 8

Wire carries the pressure and light the bulbs with the different pressures
