Topic 2 Investigating Resistance +++++

Question 1

Investigate adding resistors

Answer 1

Add resistor measure current and work out resistance
Do this each time until added 4 resistor
Plot graph

Question 2

Number of resistors against total resistance graph

Answer 2

Look on paper

Question 3

Investigate adding resistors in parallel

Answer 3

Measure total current calculate resistance
Add another resistor in parrael
Repeat calculations
Plot graph

Question 4

Number of resistors against total resistance parallel

Answer 4

Look on paper

Question 5

Resistors in series

Answer 5

Increases total resistance
Decreases risk current
More resistors added the larger the resistance becomes

Question 6

Resistors in parral

Answer 6

The town current increase
Total resistance decreases
More resistors you add the smaller the overall resistance becomes
