Answer 2

Anyone there?

Answer 3

okay so to a Cathode in the CRT, would you normally connect DC current or AC current

Answer 4

ok?

Answer 5

thats a question lol

Answer 6

well....

Answer 7

whats that

Answer 8

I need help with the entire paper..

Answer 9

i cant see that

Answer 10

okay so tell me

Answer 11

You'll Have To Download It.

Answer 12

there

Answer 13

okay look at question 1a

Answer 14

what happens when current is passed into the chatode

Answer 15

idk

Answer 16

think about it

Answer 17

what is a cathode

Answer 18

negative terminal

Answer 19

okay so when you complete the circuit

Answer 20

what will happen between the cathode and the anode

Answer 21

what u mean?

Answer 22

an electron is ejected from the cathode and goes to the anode

Answer 23

electron beam?

Answer 24

yes..

Answer 25

but you need a high enough voltage to displace an electron from the cathode

Answer 26

so when you are alternating the current during the lower voltages it will not displace an electron, this way you can control the time betweeen when your electrons are ejected, the frequency of your alternating current give you control on the frequency of ejection timings

Answer 27

an alternating current is a result of an alternating voltage and vice vera

Answer 28

question 1 b?

Answer 29

beacuse high resistance right?

Answer 30

what do you think is the answer to b

Answer 31

high resistance where

Answer 32

High resistance in the wire?

Answer 33

wire for what

Answer 34

You're going to have to be more clear if u want my help :)

Answer 35

I am not going to spoon feed you answers

Answer 36

Thick wires are used for lighting purposes because current is less?

Answer 37

higher the resistance lesser the current right?

Answer 38

the question is actually saying thick wires are used for power circuits rather than lighting purpose

Answer 39

okay lets think about this a little, why does a lightbulb light up

Answer 40

what is that fillament in the lightbulb really
