Using simply a capacitor and a resistor, the timing interval can be adjusted and so can be utilized for quite a few applications together with timers, clocks, switches, safety alarms and tone mills. An thought for an EEI could be to test the accuracy of the timing circuit.

So when you could measure the stress within the string with a force sensor and capture the information with a laboratory interface, a plot of drive vs. time should give you the peaks that you need. For a typical hand-held torch working at say 6V DC, the combination of frequencies should be such that the color appears white to the eyes. At low voltages – and therefore low filament temperatures – the filament glows a boring pink, however because the voltage is increased, the temperature additionally increases. This elevated temperature not only produces “whiter” mild as … Read More

In most applications an alternating present is applied, driving steady oscillations. If these are at the pure oscillatory frequency, resonance will occur.

Introducing the resistor increases the decay time of these oscillations, and reduces the height resonant frequency. Get maintain of a high definition video, and excessive speed with frame rates 240fps, 480fps and 1000fps . Several skilled physics teachers agreed with a colleague’s remark “I haven’t found something but that we can’t do with 300 fps”. The Casio EXILIM ZR100 High Speed Digital Camera (about $300) is fantastic in accordance with physics teachers who have used them for movement capture. Refraction in ice is determined by the wavelength of sunshine being used. For occasion the RI (at -7°C) is 1.313 for violet light falling to 1.308 for red gentle and 1.280 in the Near IR but then goes up. This isn’t a suitable variable for a high school lab.… Read More
