Answer 8

the flow of charged particles

Question 9

what is voltage

Answer 9

provides energy for electrons to flow`

Question 10

resistance

Answer 10

hinders the flow of electrons

Question 11

what are the 2 ways circuits can be connected

Answer 11

series and parallel

Question 12

what is a series circuit

Answer 12

when components in a circuit is connected one after another

Question 13

what will happen if there is a break in a series circuit

Answer 13

no current flow through the other components

Question 14

what is parallel circuit

Answer 14

when the components are collected in parallel there is more than one route that the current can take to move around the circuits

Question 15

what will happen if there is a break in a parallel circuit

Answer 15

current can still flow in other parallel parts of the circuit

Question 16

why is parallel circuits more useful than series circuit

Answer 16

bc switching off one one appliance does not mean switching off all the others

Question 17

what is electromotive(emf)

Answer 17

the source gives electrical energy each electron moving in a circuit

Question 18

unit of emf

Answer 18

volt

Question 19

what is an electrical energy difference called

Answer 19

potential difference
