capacitor charge and discharge

Capacitor charge and discharge The voltage & current of a capacitor are measured as it charges and discharges. Sensors allow a graph to be plotted as this happens. The effect of different values of...

current and voltage

Current-Voltage relationships In this experiment the resistance of a lamp, resistor or diode is measured as the current is varied. Voltage and current sensors make the measurements while the software plots the results in...

characteristics of a thermistor

Thermistor characteristics The voltage & current of a thermistor are measured as its temperature changes. Sensors allow graphs of voltage and current to be plotted against time. Not only can the resistance of the...

heating effect of an electric current

Heating effect of an electric current The temperature, voltage & current of a heating unit are measured over a period of time. This allows us to calculate the power of the heater (voltage x...

current-voltage relationships

In this experiment the resistance of a lamp, resistor or diode is measured as the current is varied. Voltage and current sensors make the measurements while the software plots the results in real-time. After...
