electricity - series circuits

Question 1

what makes a circuit a series circuit

Answer 1

there are no branches and the current can only flow in one path

Question 2

what is an electric current

Answer 2

a flow of electric charge around a circuit

Question 3

what is the unit of electric current

Answer 3

amps

Question 4

what can we use to measure the electrical current

Answer 4

ammeter

Question 5

true or false
current is never used up in a circuit and in a series circuit the current is the same all the way round

Answer 5

true

Question 6

what happens if you close the switch in a circuit

Answer 6

electrons can flow around the circuit

Question 7

which way does the current flow

Answer 7

from the negative end of the cell to the positive end

Question 8

The cell has a _____ of chemical _____ which gets transferred to ________ energy carried by the ________ passing out the ____

Answer 8

the cell has a store of chemical energy which gets transferred to electrical energy carried by the electrons passing out the cell

Question 9

what does the potential difference of 1 volt tell us

Answer 9

that 1 joule of energy is transferred for each coulomb of charge that moves through the circuit

Question 10

if the potential difference across the cell is 9.0V what would be the potential difference over two components such as lamps

Answer 10

both lamps would have a potential difference of 4.5V
this means that the light from the lamps would be dimmer
