Circuit diagrams and resistance

Question 1

what is a parallel circuit

Answer 1

this is were a circuit is setup so that each electrical device has its own pathways

Question 2

what is a complex circuit

Answer 2

it has a combination of in series and in parallel

Question 3

what are resistors

Answer 3

materials that offer electric resistance

Question 4

what is resistance

Answer 4

the ratio of the potential difference to the current for a components

Question 5

the resistance formula

Answer 5

R=V/T

Question 6

What are some of the factors that affect resistance

Answer 6

1.temperature of the wire
2.length of a wire
3.size of the potential difference across the ends of a wire
4.cross sectional area of the wire
5.resistivity

Question 7

what are non-ohomic resistors

Answer 7

resistors that do not follow ohms law

Question 8

the thicker the wire the lower the resistance

Answer 8

more current in thicker wires there fore the lower the resistance cause more electrons move in the thicker wires

Question 9

how temperature affect resistance

Answer 9

as temperature RISES resistance fall of the metal
cause metal ions in the wire vibrate vibrating less ,
but when the temperature of rise the resistances increase cause ions in this wire vibrate rapidly electrons cant move easily

Question 10

if length increases what happens to resistance

Answer 10

resistance increases

Question 11

the large the resisitance

Answer 11

the harder it is for curent to flow through the object
