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...

characteristics of a thermistor

A thermistor is an electronic component whose resistance changes with temperature. The voltage and current of a thermistor can be measured as the temperature changes. Sensors allow you to take the many readings necessary...

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...

capacitor discharge

The voltage and current in a circuit change when a capacitor charges and discharges. Computer sensors can measure these changes and software can plot a graph as fast as this happens. Also, the effect...
