• You have mentioned the difference between current and voltage very well. One of the differences between AC electricity and DC electricity is that AC electricity varies with time. But DC current always has the same value and its change over time is not observed. You have mentioned the differences between AC motor and DC motor very well.

• You have highlighted the difference between star delta forward reverse bias. Forward bias is essentially positive and reverse bias is essentially negative. Forward and reverse bias are considerations in star delta motor operation.
  Provided name and picture of switch gear in your house. Mentioned details with picture, mentions fuse and distribution board.But the first picture is not clear.

• You have mastered the values in the motor mentioned in the picture quite well. Among the mentioned values identified rpm, power factor, voltage, frequency etc. Your identifications were accurate.

• You were asked to find the current in a 5 horse power up motor as per the instructions given in the lesson. You can easily calculate current equals, power divided voltage times cosine value. The drawn circuit diagrams and device names are correct but a bit fuzzy. You can make the presentation of texts more clear.
