series and parallel circuits

Question 1

what are 2 ways that a component can be connected in a circuit

Answer 1

1. series
2. parallel

Question 2

how does the potential difference between two components vary when connected in series and parallel

Answer 2

series= total potential difference is shared between each componenent

parallel- potential difference between each component is the same

Question 3

if two resistors are connected in parallel , what can be said about their combined total resistance

Answer 3

their total resistance is less than the smallest of the two individual resistances

Question 4

if two resistors are connected in a series , what can be said about their total resistance

Answer 4

their total combined resistance is equal to the sum of two individual resistances

Question 5

describe the current in a series circuit

Answer 5

the current is the same , at all positions since the charge only has one path to flow through

Question 6

describe the current in a parallel circuit

Answer 6

. the current is shared between the different branches. when the charge reaches a junction it splits.

Question 7

how should u connect a ammeter in a circuit to measure current

Answer 7

ammeters should be connected in series with the component that they are measuring current through

Question 8

how should u connect a voltmeter in a circuit to measure potential difference

Answer 8

voltmeters should be connected in parallel to the component that they are measuring the potential difference off

Question 9

why is it advantegous to connect lamps in parallel

Answer 9

if one lamp blows,the rest will be unaffected and can still recieve current
