capacitor charge and discharge
visitors this year: 134Capacitor 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...
current and voltage
visitors this year: 169Current-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...
characteristics of a thermistor
visitors this year: 182Thermistor 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...
heating effect of an electric current
visitors this year: 99Heating 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...
