[SOLVED] Electrical characteristics of a lamp. Experiment.
GCSE Science...
Electrical characteristics of a lamp.
The Aim is to investigate the relationship between current, voltage and resistance in a lamp.
Method:
1) Set up the circuit as in the diagram (with three cells)
2) Set the variable resistor to maximum
3) Measure the voltage and current of the circuit
4) Repeat as many times as you see fit and record the data, decreasing the resistance using the variable resistor.
I couldn't get the accurate results... and I seriously don't get it.
What's supposed to happen in this experiment?
