Review implementation and measurements in Edexcel A-Level Physics through method improvements, data logging, video analysis and accuracy decisions.
Two identical capacitors were connected in series and charged. They were then discharged through a resistor and ammeter.
A student investigated how the current in the resistor varied as the capacitors discharged.
The student repeated the investigation but used a data logger instead of a stopwatch and an ammeter.
Suggest why using a data logger would improve this investigation.
Readings (of current and time) can be taken simultaneously
Many readings can be taken in a short time
