In this experiment, various electrochemical cells were measured and calculated to determine their electrical cell potential. In the electrochemical cell Zn (s) │Zn2+ (0.10 M) ││ Cu2+ (0.10 M) │ Cu(s), E cell potential was determined to be 1.040 V while the standard E˚ cell potential was 1.10 V. In the electrochemical cell Zn (s) │Zn2+ (0.10 M) ││ Cu2+ (1.0 M) │ Cu(s) E cell potential was determined to be 1.060 V while the standard E˚ cell potential was 1.10 V. In the electrochemical cell Cu (s)…
Feed Forward Control model in Simulink To implement feed forward control. Firstly, the transfer function of the linear DC Motor model has to be obtained. Actually in our case, the input of the plant is current so the transfer function of the mathematical model in ratio of angular velocity to current has to be obtained. It is given by: G(s)=Ω_1/I_a =R_A/K_M 1/(T_e s+1) where T_e=(J_meq R_A)/(K_m Cϕ) is electro-mechanical time constant. The feed forward control could be determined using…
How Electro-mechanical Actuator Works? A Rotary Electromechanical Actuation system with an Electric Motor, a gear box & an elastic spring to absorb peak torque loads experienced during operational life. The Schematic below describes the system. Fig. 1.1 Rotary Electro-mechanical Actuator Gearbox Requirements: The Gear Box at the Motor Output is intended to amplify the torque output of the Motor with reduction in speed. The tentative ratio is set at 10:1. Functional Requirements of…
Technological innovations had a major impact on the U.S during the Gilded Age. Our major inventors were Thomas Edison and Nicola Tesla. Thomas Edison invented the DC light bulb however, Nicola Tesla invented the AC light bulb. Tesla worked under Edison as his apprentice when he was working on the light bulb. While Tesla was under Edison, JP Morgan was trying to find an industry that he could rise from the ground, and that's when he found Edison with electricity and the light bulb. JP…
the Avo 8, possible reasons for varience include a parallax error (not looking at the reading from directly above the meter), a reading error due to less divisions when measuring resistance, or the device not being properly zeroed. When measuring current, there are also fewer division, parallax is still a potential issue, and finally, incorrect zeroing of the meter. Voltage has an additional error, the loading of the meter itself. Alongside this issue, there is also parallax, zero, and…
Thomas Edison was an amazing man, and did amazing things for the world and America. He was an inventor who worked mainly with electricity and things that will help people with everyday things. He started out small and then he grew as a business and was one of the best inventors people say. And he works with all of this stuff to make him more determined and he had his mind set on this stuff. If Thomas Edison didn’t do what he did the world wouldn’t be the same as it is now. Thomas Edison was…
alternating current which means that the current flows in both directions. So instead of flowing from one source to another, the current can flow from both the source and the recipient to each other. AC voltage is the current that comes from an electrical plug. An advantage of AC voltage is the fact that the power of the voltage can be altered with a transformer. Fig.1 graph showing AC and DC current On the other hand DC voltage stands for direct current. This means that the current only…
circuit the internal resistance of a DC source should be equal to zero for maximum power transfer to the load resistance. The derivation of the maximum power transfer theorem for resistive and non-linear impedance AC circuits. I – Phasor current (ωL or-1/ωC)_L and (ωL or-1/ωC)_r= X_L and X_r respectively I = (E_rms∠0°)/(Z+Z_r ) = (E_rms∠0°)/(r+R_L+j(X_r+X_L)) P_L= |I|^2 R_L =R_L/(〖(r+R_L)〗^2+〖(X+X_L)〗^2 ) 〖E_rms〗^2 2.1) The maximum power transfer when we have the choice to…
Do you like the vibe of grass under your feet, or the sand in the middle of your toes, well appreciate all the more unshod contact with the Earth, since that is the thing that Earthing or Grounding truly is! As a child we cherished strolling unshod all over the place... yes it was on account of it felt great on our feet, additionally in light of the fact that our bodies felt the advantages as well. In the event that we could backtrack to those days we would be in an ideal situation, the Earth…
