- Resistance
- In series and parallel,
- You can investigate resistance by adding resistors
- 1) Get at least 4 identical resistors
- 2) Build the circuit and note the voltage of the battery
- 3) Measure the current through the circuit using an ammeter
- 4) Calculate resistance = Voltage / Current
- 5) Add another resistor and measure the current and voltage to calculate resistance
- 6) Repeat until all resistors are added
- 7) Plot a graph

- 6) Repeat until all resistors are added

- 5) Add another resistor and measure the current and voltage to calculate resistance

- 4) Calculate resistance = Voltage / Current

- You can investigate resistance by adding resistors
- Adding resistors in series increases total resistance of circuit
- And decreases the total current

- The more resistors you add, the larger the resistance of the whole circuit
- When you add resistors in parallel, the total current of the circuit increases
- And the total resistance decreases
- The more resistors you add, the smaller the overall resistance becomes

- In series and parallel,
