circuits

Question 1

charge

Answer 1

value for electricity flowing through a circuit

Question 2

current

Answer 2

flow of electrons

Question 3

potential difference

Answer 3

pushes current around

Question 4

resistance

Answer 4

slows down current

Question 5

what does the current potential difference graph for a resistor look like?

Answer 5

directly proportional, diagonal line north east

Question 6

what does the current potential difference graph for a filament bulb look like?

Answer 6

as temp increases, the resistance increases. straight through zero northeast bends on each end

Question 7

what does the current potential difference graph for a diode look like?

Answer 7

only lets current flow in one direction so graph. straight line until zero. goes up north east

Question 8

a thermistor only lets current flow at?

Answer 8

certain temperatures

Question 9

we can can think of current as?

Answer 9

electrons flowing through a circuit

Question 10

in a series circuit, current…

Answer 10

flow in the same direction, so the current will be the same all throughout a series circuit

Question 11

in a parallel circuit current….

Answer 11

is split across branches.

Question 12

total potential difference in a series circuit…

Answer 12

is split across all components, so you must add them all to find total

Question 13

total potential difference in a parallel circuit…

Answer 13

same all the way through

Question 14

to find resistance in a series circuit

Answer 14

add all resistance in circuit to find total resistance

Question 15

to find resistance in a parallel circuit

Answer 15

1/R + 1/R

1/ the resistance add all
