CALCULATIONS N.A. 6. DISCUSSION The error between the experimental and theoretical slope ranges to be about 10-40%. Most of the errors are low so our results are fairly accurate. Several sources of error include, incorrect set-up of the circuit, failing to insert the banana cable in the 5V slot in a timely manner, incorrect magnitude of resistance on the resistor, and forgetting to change the Resistance value on Logger Pro. 7. CONCLUSION My group constructed and analyzed the current flowing in an RL Circuit through experimentation, using Logger Pro software. Page 7 of 7...
