investigating resistance

Question 1

how can you investigate adding resistors in series

Answer 1

1) find 4 identical resistors
2) build the circuit using one if the resistors, take not of the pd of the battery
3)measures the current through the circuit using the ammeter
4) then calculate the resistance
5)measure the current through the circuit and calculate the overall resistance
6) repeat 4-5 times
7) plot graph

Question 2

investige adding resistors in parallel

Answer 2

1) use the same equipment as in series so its a fair test , build the initial same circuit
2) measure the total current and calculate the resistance
3) and another resistor in parallel with the first
4)measure the total current and the overall resistance of the circuit
5) repeat 3-4 more times
6) plot the graph

Question 3

what should you results match

Answer 3

the resistance rules
