Investigation of the charge and discharge of the capacitor

Question 1

experimenta; arrangements

Answer 1

• capacitor charged through resistor by connecting the switch, then discharged by connecting to other temrimanl
• pd across capacitor measured by the voltage sensor and recorded by the data logger
• analysed by computer

Question 2

safety

Answer 2

• although pd is low voltage, care should be taken to avoid short circuit
• check pd compatible with voltage senspor
• danger: if an electrolytics capacitor is being used, polarity must be observed, positive end conencted to positive side
