Description

Un circuit est constitué d'un générateurdetension variable, d'une résistance R de valeur réglable etd'uneampoule en série.
Un ampèremètre placé en série permet de mesurer le courant Iducircuit et un voltmètre placée en dérivation mesure la tensionURaux bornes de la résistance.
L'ampoule réagit comme une résistance RA = 10Ω.
La courbe mesure la puissance P dissipée dans la résistance.L'unitéde la puissance est le Watt (W)
P = UR x I = R x I2
Quand la tension d'alimentation augmente, I augmente et lapuissancedissipée par R augmente.
Quand la valeur de R augmente, I diminue et la puissancedissipéepar R diminue.
La résistance réglable R permet de contrôler l'intensité ducourantdans le circuit.

The curve measures the power P dissipated in the resistor. Theunitof power is the watt (W)
UR = P x R x I = I2
When the supply voltage increases, I increases and thepowerdissipated by R increases.
When the value of R increases, I decreases and the powerdissipatedby R decreases.
The adjustable resistor R controls the current in thecircuit.

Rust 1.0 APK
eduMedia
Iron nails are placed in fiveenvironments:Tube 1: Just in airTube 2: A part of the nail is immerged in waterTube 3: A part of the nail is immerged in salt waterTube 4:The nail is completely immerged in boiling water and a layerof oil separates the water from the airTube 5: A dehydration product (Calcium chloride or Copper Sulfate)absorbes the humidity contained in the air.The different hypotheses or this experiment allow us to explain theformation of rust:Only the nails in the three tubes on the left rust, at a fast rate.The two experiments on the right slow down or stop the formation ofrust.This allows us to confirm that iron does not rust until it is incontact with air and water.

Crookes Tube 1.0 APK

This animation describes J. J. Thomson’ssecond experiment involving the deviation of an electron beam in avacuum tube, called a Crookes Tube.A partial vacuum (less than 10-6 atm) is maintained in the tube. Ahigh voltage (between 10 and 100 kV) is applied between twoelectrodes. The very intense electric field that results from thisaccelerates the few ions present in the tube which, via coliisions,ionize other particles. The lower the pressure , the more theelectrons thus liberated and accelerated travel great distancesuntil they strike the screen at the opposite end of the tube.By studying the deviation of this beam, J. J. Thomson, in 1897,isolated a new elementary particle carrying a negative charge – theelectron.This apparatus constitutes the first particle accelerator. As aresult of his work, Thomson proposed a completely new model of theatom (Thomson’s Plum Pudding Model) that one of his students,Ernest Rutherford, would improve upon 10 years later.Click and drag the cursor to change the intensity of the voltageapplied between the plates.

Power dissipated by a resistor 1.0 APK
eduMedia
The circuit is made up of a variable powersupply, a variable resistor R and, a light bulb all connected inseries.An ammeter, placed in series, allows the current, I, to bemeasured. A voltmeter connected in parallel with the resistor, R,allows the voltage across the resistor VR to be measured.The light bulb acts like a resistor, RA, with resistance equal to10Ω.The curve shows the power dissipated in the the resistor. The unitof power is the Watt (W).P = VR x I = R x I2When the voltage is increased, the current, I, increases and thepower dissipated by the resistor, R, increases.When the value of the resistor is increased, I decreases and thepower dissipated by the resistor, R, decreases.The variable resistor, R, allows control of the current intensityin the circuit.Slide the cursor on the voltage and/or resistance tab toestablish the desired values.
