physics chapter 13

Question 1

AC/Alternating current

Answer 1

direction of electrons switches within s regular routine

Question 2

which way do the electrons flow in a circuit?

Answer 2

toward the positive terminal and away from the negative terminal (opposites attract)

Question 3

series circuit vs parallel circuit?

Answer 3

series has only one path for electrons while parallel has multiple

Question 4

what is current measured in?

Answer 4

amprees/I

Question 5

what is potential difference measured in?

Answer 5

volts

Question 6

what is resistance measured in?

Answer 6

ohms

Question 7

what is charge mesured in?

Answer 7

coulombs

Question 8

electrical current?

Answer 8

charge that passes a point in a conducting wire each second

Question 9

formula for current?

Answer 9

charge moving past a point (coulombs) / time in seconds

Question 10

voltage formula

Answer 10

energy (joules) / charge (coulombs)

Question 11

you have 45 joules in a battery and 15c of charge… what is the potential difference/ voltage of the battery?

Answer 11

use the grass method
45/15
the potential difference would be 3V

Answer 12

6.25x10^18

Question 13

what is the conversions of milliamps to amps

Answer 13

1000 milliamps for every amp

Question 14

what is the conversion from 1 killivolt to volts

Answer 14

1 kv for every 1000 volts

Question 15

what is the scientific notation of 46,000

Answer 15

4.6x10^4

move the decimal place the amount of the exponent to the right

Question 16

how many volst is 3.2x10^3

Answer 16

write the number with the decimal place moved to the right the number of times as the exponent
3200

Question 17

calculating resistance formula triangle

Answer 17

v=i x r
i=v / r
r=v / i
