capacitor charge and discharge

visitors this year: 59 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...

current and voltage

visitors this year: 77 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: 77 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...

battery life

visitors this year: 39 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: 136 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...

current-voltage relationships

visitors this year: 53 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...

capacitor discharge

visitors this year: 44 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: 42 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: 65 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...
