Checkpoint (p.197) 1. The heating effect of current increases with the applied voltage across the wire. Microscopically‚ when a voltage is applied across the ends of a metal wire‚ an electric field is set up between the ends. The free electrons are accelerated by the field and collide frequently with the metal ions in the wire. Thus‚ some energy is transformed into the internal energy of the wire. When the applied voltage increases‚ the electric field is stronger. The electrons collide harder as

Resistance (W) Copper 0.2mm 1.8 W Constantan 0.2mm 9.1 W Constantan 0.45mm 5 W Constantan 0.9mm 1.8 W Diagram: The things that I will measure and observe are the voltage running through the wire and the current. This will allow me to calculate the resistance of the wire. To calculate the resistance of the wire I will divide the voltage (V) by the current (I)‚ which will give me the resistance in ohms (W). Equipment: The equipment that I will use is: - power pack - ammeter - voltmeter - 30 SWG

The values also were shown clearly by the device. The last one‚ which is objective C‚ is to help us familiarize with the function generator and oscilloscope. The values for the first half were still clear but it seemed that the AC voltage differ hugely to the other voltages. While turning the position knobs to shift the cursors at either the peak or complete cycle of the wave‚ there formed the delta which has significantly agreed to the true value of what it measures. CONCLUSION I conclude that

TLE Electron The electron (symbol: e−) is a subatomic particle with a negative elementary electric charge. An electron has no known components or substructure. It is generally thought to be an elementary particle.[2] An electron has a mass that is approximately 1/1836 that of the proton. The intrinsic angular momentum (spin) of the electron is a half-integer value in units of ħ‚ which means that it is a fermion. The antiparticle of the electron is called the positron; it is identical to the

output of this particular batch of power transformers have a higher output voltage than they are rated and sold for. You should have been immediately notified of this issue and I apologize that our usual highest-quality customer service communication methods have failed to be met. In effort to put an end to these types of errors‚ we have changed our assembly process to include the testing and verification of the output voltages in the powers transformers we use in our products. We highly value

potential by changing the membrane permeability allowing the sodium and potassium ions to pass through. At different levels of stimulation the motor neurons stimulate a motor unit and the more stimulation the more motor units become active. When the voltage was set at 0 or .1 there was no reaction because the shock wasn’t able to trigger the threshold for action potential production. The lowest reaction with shock was .3 volts created by a contraction of a low number of the fibers in the muscle. When
