Required Practical - Investigating Resistance

• 1. Find 4 identical resistors
• 2) Build a circuit and make a note of the potential difference of the battery
• 3) Measure the current through the circuit using the ammeter and use this to calculate the resistance of the circuit
• 4) Add another resistor in series with the first
• 5) Measure the current and use this and the potential difference if the battery and calculate the overall resistance of the circuit
