current and voltage
visitors this year: 136 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...
characteristics of a thermistor
visitors this year: 143 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...
heating effect of an electric current
visitors this year: 68 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...
battery life
visitors this year: 70 Battery life In this experiment an electrical cell is tested to exhaustion. The cell might be a dry-cell, an alkaline cell or a lead-acid accumulator. The decreasing voltage is measured...
characteristics of a thermistor
visitors this year: 214 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...

capacitor discharge
visitors this year: 92 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...
types of battery 2
visitors this year: 118 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...
voltage & current sensors
visitors this year: 141 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...
