Voltage - Differential 20V
type: Product
description: Monitor voltage over a fast short or long slow period of time in addition to spot measurements. 53-sec capacitor - charge & discharge Teaching applications: Introductory electricity Ohm’s law Simple series and parallel circuits Startup of a filament lamp Extension and advanced ideas: Induction of voltage in a coil Electrical characteristics of components Voltage and homemade sensors Dynamo effect Time constant, charge discharge of a capacitor Download Voltage Sensor Manual Doc No.: DS021 | Issue: 6 Contents/Details: ±20 V (Resolution 10 mV) Maximum Voltage ±27 V, Impedance 1 Meg ohm Voltage sensors measure the potential difference between the ends of an electrical component and are connected in parallel. They can be used to measure both DC and low-voltage AC circuits. They should never be used with high voltages or household AC. The 4 mm plugs attach to most standard school’s electronics kits and power supplies. A Voltage Sensor can be used in conjunction with a Current Sensor. Batteries are the first choice as the source of energy. An alternative is to use a fully isolated mains power supply with a regulated DC output (smoothed and fully rectified). Be aware that some power supplies are ½ wave rectified producing an average rather than true DC, this sensor will ‘pick up’ the fluctuations in voltage and current from this type of power supply. Physics Electricity from water power (Physics (11-14) eBook) Use a simple water wheel to make electricity via generator. Monitor the voltage and or current over time against other variables e.g. flow, fall height etc. Light and voltage (Physics (11-14) eBook) Investigations with simple solar cells. Voltage produced, current, effect of light intensity, insolation angle etc. Current and voltage in a series circuit (Physics (11-14) eBook) This one of a series of investigations into current in a circuit. This part requires additional lamps and or cells to be added and the changes measured. Electrical Equivilence Of Heat (Physics (1…
