Saad - Assignment Example(b). A capacitor is constructed as dickens plane parallel square plates with an area of 20cm* 20cm and a 5.0mm separation. It is mounted in a vertical plane (with the top plate edges horizontal) and used to measure the depth of liquid in a tank, which is allowed to fill the space between the plates to a covariant extent, the rest being filled with air.If the liquid is methanol with a relative permittivity of 33, calculate the maximum and minimum comforts of the capacitance, corresponding to the extreme liquid levels, and the value when the gap is half-full.(c). To avoid rapid indicator fluctuations if the liquid is agitated when half-full, a time constant for change/discharge of about 10s is required. What should be the series immunity of the electrical supply to the capacitor?A generator is basically a machine that has ability to convert mechanical energy into electrical energy. We have two types of generators depending on the types of electric current t hey produce. We have either direct current (DC) or alternating current (AC) generators. These two types of generators have differing construction details that the basic principle on the way they work is similar.Shunt-wound generator or Penjana Piran is a type of generator where field winding is connected parallel to the armature and then creating a relatively high resistance making the current carried to be a only as fraction of the armature
