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

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

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

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

The ethical violations found in the original experiment (1962) included participants (teacher) giving other participants (learner) dangerous electrical shocks at a very high voltage increasing all the way up to 450 volts. The experimenter (authority) informed both the teacher and the learner participants that although the volts may be painful‚ they are not dangerous. Even though the “teacher” could hear the “learner” yell and scream as they got shocked each time‚ the “teacher” continued with the
