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...

types of battery 2

Batteries or electrical cells are made using different substances. There are zinc dry-cells, alkaline cells and lead-acid accumulators. When you use them, the chemicals become exhausted at different rates. So choosing the right battery...

voltage & current sensors

The scope for electrical measurement as obviously as big as the subject itself. Data logging systems tend to measure changes over time and that suits these sensors to measuring the life of a battery,...
